+When reviewing code, focus on:
+
+## Security Critical Issues
+- Check for hardcoded secrets, API keys, or credentials.
+- Check for instances of potential method call injection, dynamic code execution, symbol injection or other code injection vulnerabilities.
+
+## Performance Red Flags
+- Spot inefficient loops and algorithmic issues.
+- Check for memory leaks and resource cleanup.
+
+## Code Quality Essentials
+- Methods should be focused and appropriately sized. If a method is doing too much, suggest refactorings to split it up.
+- Use clear, descriptive naming conventions.
+- Avoid encapsulation violations and ensure proper separation of concerns.
+- All public classes, modules, and methods should have clear documentation in Sphinx format.
+
+## PyMongo-specific Concerns
+- Do not review files within `pymongo/synchronous` or files in `test/` that also have a file of the same name in `test/asynchronous` unless the reviewed changes include a `_IS_SYNC` statement. PyMongo generates these files from `pymongo/asynchronous` and `test/asynchronous` using `tools/synchro.py`.
+- All asynchronous functions must not call any blocking I/O.
+
+## Review Style
+- Be specific and actionable in feedback.
+- Explain the "why" behind recommendations.
+- Acknowledge good patterns when you see them.
+- Ask clarifying questions when code intent is unclear.
+
+Always prioritize security vulnerabilities and performance issues that could impact users.
+
+Always suggest changes to improve readability and testability. For example, this suggestion seeks to make the code more readable, reusable, and testable:
+
+```python
+# Instead of:
+if user.email and "@" in user.email and len(user.email) > 5:
+    submit_button.enabled = True
+else:
+    submit_button.enabled = False
+
+# Consider:
+def valid_email(email):
+    return email and "@" in email and len(email) > 5
+
+
+submit_button.enabled = valid_email(user.email)
+```

+# Contributing to PyMongo
+
+PyMongo has a large
+[community](https://pymongo.readthedocs.io/en/stable/contributors.html)
+and contributions are always encouraged. Contributions can be as simple
+as minor tweaks to the documentation. Please read these guidelines
+before sending a pull request.
+
+## Bugfixes and New Features
+
+Before starting to write code, look for existing
+[tickets](https://jira.mongodb.org/browse/PYTHON) or [create
+one](https://jira.mongodb.org/browse/PYTHON) for your specific issue or
+feature request. That way you avoid working on something that might not
+be of interest or that has already been addressed.
+
+## Supported Interpreters
+
+PyMongo supports CPython 3.9+ and PyPy3.9+. Language features not
+supported by all interpreters can not be used.
+
+## Style Guide
+
+PyMongo follows [PEP8](http://www.python.org/dev/peps/pep-0008/)
+including 4 space indents and 79 character line limits.
+
+## General Guidelines
+
+-   Avoid backward breaking changes if at all possible.
+-   Write inline documentation for new classes and methods.
+-   We use [uv](https://docs.astral.sh/uv/) for python environment management and packaging.
+-   We use [just](https://just.systems/man/en/) as our task runner.
+-   Write tests and make sure they pass (make sure you have a mongod
+    running on the default port, then execute `just test` from the cmd
+    line to run the test suite).
+-   Add yourself to doc/contributors.rst `:)`
+
+## Authoring a Pull Request
+
+**Our Pull Request Policy is based on this** [Code Review Developer
+Guide](https://google.github.io/eng-practices/review)
+
+The expectation for any code author is to provide all the context needed
+in the space of a pull request for any engineer to feel equipped to
+review the code. Depending on the type of change, do your best to
+highlight important new functions or objects you've introduced in the
+code; think complex functions or new abstractions. Whilst it may seem
+like more work for you to adjust your pull request, the reality is your
+likelihood for getting review sooner shoots up.
+
+**Self Review Guidelines to follow**
+
+-   If the PR is too large, split it if possible.
+
+    - Use 250 LoC (excluding test data and config changes) as a
+            rule-of-thumb.
+
+     - Moving and changing code should be in separate PRs or commits.
+
+        -   Moving: Taking large code blobs and transplanting
+            them to another file. There\'s generally no (or very
+            little) actual code changed other than a cut and
+            paste. It can even be extended to large deletions.
+        -   Changing: Adding code changes (be that refactors or
+            functionality additions/subtractions).
+        -   These two, when mixed, can muddy understanding and
+            sometimes make it harder for reviewers to keep track
+            of things.
+
+-   Prefer explaining with code comments instead of PR comments.
+
+**Provide background**
+
+-   The PR description and linked tickets should answer the "what" and
+    "why" of the change. The code change explains the "how".
+
+**Follow the Template**
+
+-   Please do not deviate from the template we make; it is there for a
+    lot of reasons. If it is a one line fix, we still need to have
+    context on what and why it is needed.
+
+-   If making a versioning change, please let that be known. See examples below:
+
+    -   `versionadded:: 3.11`
+    -   `versionchanged:: 3.5`
+
+### AI-Generated Contributions Policy
+
+#### Our Stance
+
+We only accept pull requests that are authored and submitted by human contributors who fully understand the changes they are proposing. Pull requests that are not clearly owned and understood by a human contributor may be closed. **All contributions must be submitted, reviewed, and understood by human contributors.**
+
+##### Why This Policy Exists
+
+At MongoDB, we understand the power and prevalence of AI tools in software development. With that being said, many MongoDB libraries are foundational tools used in production systems worldwide. The nature of these libraries requires:
+
+- **Deep domain expertise**: MongoDB's wire protocol, BSON specification, connection pooling, authentication mechanisms, and concurrency patterns require an understanding that AI alone cannot substantiate.
+
+- **Long-term maintainability**: Contributors need to be able to explain *why* code is written a certain way, explain design decisions, and be available to iterate on their contributions.
+
+- **Security responsibility**: Authentication, credential handling, and TLS implementation cannot be left to probabilistic code generation.
+
+##### What This Means for Contributors
+
+**Required:**
+
+- Full understanding of every line of code you submit
+- Ability to explain and defend your implementation choices
+- Willingness to iterate and maintain your contributions
+
+**Encouraged:**
+
+- Using AI assistants as learning tools to understand concepts
+- IDE autocomplete features that suggest standard patterns
+- AI help for brainstorming approaches (but write the code yourself)
+- Writing code using AI tools, reviewing each line and revising code as necessary.
+
+**Not allowed:**
+
+- Submitting PRs generated solely by AI tools
+- Copy-pasting AI-generated code without full understanding
+
+##### Disclosure
+
+If you used AI assistance in any way during your contribution, please disclose what the AI assistant was used for in your PR description. We would love to know what tools developers have found useful in iterating in their day to day.
+
+##### Questions?
+
+If you're unsure whether your contribution complies with this policy, please ask for guidance within the scope of the PR and clarify any uncertainty. We're happy to guide contributors toward successful contributions.
+
+---
+
+*This policy helps us maintain the reliability, security, and trustworthiness that production applications depend on. Thank you for understanding and for contributing thoughtfully to PyMongo.*
+
+## Running Linters
+
+PyMongo uses [pre-commit](https://pypi.org/project/pre-commit/) for
+managing linting of the codebase. `pre-commit` performs various checks
+on all files in PyMongo and uses tools that help follow a consistent
+code style within the codebase.
+
+To set up `pre-commit` locally, run:
+
+```bash
+brew install pre-commit
+pre-commit install
+```
+
+To run `pre-commit` manually, run:
+
+```bash
+pre-commit run --all-files
+```
+
+To run a manual hook like `ruff` manually, run:
+
+```bash
+pre-commit run --all-files --hook-stage manual ruff
+```
+
+Typically we use `just` to run the linters, e.g.
+
+```bash
+just install  # this will install a venv with pre-commit installed, and install the pre-commit hook.
+just typing-mypy
+just run lint-manual
+```
+
+## Documentation
+
+To contribute to the [API documentation](https://pymongo.readthedocs.io/en/stable/) just make your
+changes to the inline documentation of the appropriate [source code](https://github.com/mongodb/mongo-python-driver) or
+[rst file](https://github.com/mongodb/mongo-python-driver/tree/master/doc) in
+a branch and submit a [pull request](https://help.github.com/articles/using-pull-requests). You
+might also use the GitHub
+[Edit](https://github.com/blog/844-forking-with-the-edit-button) button.
+
+We use [reStructuredText](https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html) for all
+documentation including narrative docs, and the [Sphinx docstring format](https://sphinx-rtd-tutorial.readthedocs.io/en/latest/docstrings.html).
+
+You can build the documentation locally by running:
+
+```bash
+just docs
+```
+
+When updating docs, it can be helpful to run the live docs server as:
+
+```bash
+just docs-serve
+```
+
+Browse to the link provided, and then as you make changes to docstrings or narrative docs,
+the pages will re-render and the browser will automatically refresh.
+
+## Running Tests Locally
+
+-   Run `just install` to set a local virtual environment, or you can manually
+    create a virtual environment and run `pytest` directly.  If you want to use a specific
+    version of Python, set `UV_PYTHON` before running `just install`.
+-   Ensure you have started the appropriate Mongo Server(s).  You can run `just run-server` with optional args
+    to set up the server.  All given options will be passed to
+    [`run-mongodb.sh`](https://github.com/mongodb-labs/drivers-evergreen-tools/blob/master/.evergreen/run-mongodb.sh).  Run `$DRIVERS_TOOLS/.evergreen/run-mongodb.sh start -h`
+    for a full list of options.
+-   Run `just test` or `pytest` to run all of the tests.
+-   Append `test/<mod_name>.py::<class_name>::<test_name>` to run
+    specific tests. You can omit the `<test_name>` to test a full class
+    and the `<class_name>` to test a full module. For example:
+    `just test test/test_change_stream.py::TestUnifiedChangeStreamsErrors::test_change_stream_errors_on_ElectionInProgress`.
+-   Use the `-k` argument to select tests by pattern.
+-   Run `just test-coverage` to run tests with coverage and display a report. After running tests with coverage, use `just coverage-html` to generate an HTML report in `htmlcov/index.html`.
+
+
+## Running tests that require secrets, services, or other configuration
+
+### Prerequisites
+
+- Clone `drivers-evergreen-tools`:
+    `git clone git@github.com:mongodb-labs/drivers-evergreen-tools.git`.
+- Run `export DRIVERS_TOOLS=$PWD/drivers-evergreen-tools`.  This can be put into a `.bashrc` file
+  for convenience.
+- Some tests require access to [Drivers test secrets](https://github.com/mongodb-labs/drivers-evergreen-tools/tree/master/.evergreen/secrets_handling#secrets-handling).
+
+### Usage
+
+- Run `just run-server` with optional args to set up the server.
+- Run `just setup-tests` with optional args to set up the test environment, secrets, etc.
+  See `just setup-tests -h` for a full list of available options.
+- Run `just run-tests` to run the tests in an appropriate Python environment.
+- When done, run `just teardown-tests` to clean up and `just stop-server` to stop the server.
+
+### SSL tests
+
+- Run `just run-server --ssl` to start the server with TLS enabled.
+- Run `just setup-tests --ssl`.
+- Run `just run-tests`.
+
+Note: for general testing purposes with an TLS-enabled server, you can use the following (this should ONLY be used
+for local testing):
+
+```python
+from pymongo import MongoClient
+
+client = MongoClient(
+    "mongodb://localhost:27017?tls=true&tlsAllowInvalidCertificates=true"
+)
+```
+
+If you want to use the actual certificate file then set `tlsCertificateKeyFile` to the local path
+to `<repo_roo>/test/certificates/client.pem` and `tlsCAFile` to the local path to `<repo_roo>/test/certificates/ca.pem`.
+
+### Encryption tests
+
+- Run `just run-server` to start the server.
+- Run `just setup-tests encryption`.
+- Run the tests with `just run-tests`.
+
+To test with `encryption` and `PyOpenSSL`, use `just setup-tests encryption pyopenssl`.
+
+### PyOpenSSL tests
+
+- Run `just run-server` to start the server.
+- Run `just setup-tests default_sync pyopenssl`.
+- Run the tests with `just run-tests`.
+
+Note: `PyOpenSSL` is not used in async tests, but you can use `just setup-tests default_async pyopenssl`
+to verify that PyMongo falls back to the standard library `OpenSSL`.
+
+### Load balancer tests
+
+- Install `haproxy` (available as `brew install haproxy` on macOS).
+- Start the server with `just run-server load_balancer`.
+- Set up the test with `just setup-tests load_balancer`.
+- Run the tests with `just run-tests`.
+
+### AWS auth tests
+
+- Run `just run-server auth_aws` to start the server.
+- Run `just setup-tests auth_aws <aws-test-type>` to set up the AWS test.
+- Run the tests with `just run-tests`.
+
+### OIDC auth tests
+
+- Run `just setup-tests auth_oidc <oidc-test-type>` to set up the OIDC test.
+- Run the tests with `just run-tests`.
+
+The supported types are [`default`, `azure`, `gcp`, `eks`, `aks`, and `gke`].
+For the `eks` test, you will need to set up access to the `drivers-test-secrets-role`, see the [Wiki](https://wiki.corp.mongodb.com/spaces/DRIVERS/pages/239737385/Using+AWS+Secrets+Manager+to+Store+Testing+Secrets).
+
+### KMS tests
+
+For KMS tests that are run locally, and expected to fail, in this case using `azure`:
+
+- Run `just run-server`.
+- Run `just setup-tests kms azure-fail`.
+- Run `just run-tests`.
+
+For KMS tests that run remotely and are expected to pass, in this case using `gcp`:
+
+- Run `just setup-tests kms gcp`.
+- Run `just run-tests`.
+
+### Enterprise Auth tests
+
+Note: these tests can only be run from an Evergreen host.
+
+- Run `just run-server enterprise_auth`.
+- Run `just setup-tests enterprise_auth`.
+- Run `just run-tests`.
+
+### Atlas Connect tests
+
+- Run `just setup-tests atlas_connect`.
+- Run `just run-tests`.
+
+### Search Index tests
+
+- Run `just run-server search_index`.
+- Run `just setup-tests search_index`.
+- Run `just run-tests`.
+
+### MockupDB tests
+
+- Run `just setup-tests mockupdb`.
+- Run `just run-tests`.
+
+### Doc tests
+
+The doc tests require a running server.
+
+- Run `just run-server`.
+- Run `just setup-tests doctest`.
+- Run `just run-tests`.
+
+### Free-threaded Python Tests
+
+In the evergreen builds, the tests are configured to use the free-threaded python from the toolchain.
+Locally you can run:
+
+- Run `just run-server`.
+- Run `just setup-tests`.
+- Run `UV_PYTHON=3.14t just run-tests`.
+
+### AWS Lambda tests
+
+You will need to set up access to the `drivers-test-secrets-role`, see the [Wiki](https://wiki.corp.mongodb.com/spaces/DRIVERS/pages/239737385/Using+AWS+Secrets+Manager+to+Store+Testing+Secrets).
+
+- Run `just setup-tests aws_lambda`.
+- Run `just run-tests`.
+
+### mod_wsgi tests
+
+Note: these tests can only be run from an Evergreen Linux host that has the Python toolchain.
+
+- Run `just run-server`.
+- Run `just setup-tests mod_wsgi <mode>`.
+- Run `just run-tests`.
+
+The `mode` can be `standalone` or `embedded`.  For the `replica_set` version of the tests, use
+`TOPOLOGY=replica_set just run-server`.
+
+### OCSP tests
+
+- Export the orchestration file, e.g. `export ORCHESTRATION_FILE=rsa-basic-tls-ocsp-disableStapling.json`.
+This corresponds to a config file in `$DRIVERS_TOOLS/.evergreen/orchestration/configs/servers`.
+MongoDB servers on MacOS and Windows do not staple OCSP responses and only support RSA.
+NOTE: because the mock ocsp responder MUST be started prior to the server starting, the ocsp tests start the server
+as part of `setup-tests`.
+
+- Run `just setup-tests ocsp <sub test>` (options are "valid", "revoked", "valid-delegate", "revoked-delegate").
+- Run `just run-tests`
+
+If you are running one of the `no-responder` tests, omit the `run-server` step.
+
+### Perf Tests
+
+- Start the appropriate server, e.g. `just run-server --version=v8.0-perf --ssl`.
+- Set up the tests with `sync` or `async`: `just setup-tests perf sync`.
+- Run the tests: `just run-tests`.
+
+## Enable Debug Logs
+
+- Use `-o log_cli_level="DEBUG" -o log_cli=1` with `just test` or `pytest` to output all debug logs to the terminal. **Warning**: This will output a huge amount of logs.
+- Add `log_cli=1` and `log_cli_level="DEBUG"` to the `tool.pytest.ini_options` section in `pyproject.toml` to enable debug logs in this manner by default on your machine.
+- Set `DEBUG_LOG=1` and run `just setup-tests`, `just-test`, or `pytest` to enable debug logs only for failed tests.
+- Finally, you can use `just setup-tests --debug-log`.
+- For evergreen patch builds, you can use `evergreen patch --param DEBUG_LOG=1` to enable debug logs for failed tests in the patch.
+
+## Testing minimum dependencies
+
+To run any of the test suites with minimum supported dependencies, pass `--test-min-deps` to
+`just setup-tests`.
+
+## Testing time-dependent operations
+
+- `test.utils_shared.delay` - One can trigger an arbitrarily long-running operation on the server using this delay utility
+  in combination with a `$where` operation. Use this to test behaviors around timeouts or signals.
+
+## Adding a new test suite
+
+- If adding new tests files that should only be run for that test suite, add a pytest marker to the file and add
+  to the list of pytest markers in `pyproject.toml`.  Then add the test suite to the `TEST_SUITE_MAP` in `.evergreen/scripts/utils.py`.  If for some reason it is not a pytest-runnable test, add it to the list of `EXTRA_TESTS` instead.
+- If the test uses Atlas or otherwise doesn't use `run-mongodb.sh`, add it to the `NO_RUN_ORCHESTRATION` list in
+  `.evergreen/scripts/utils.py`.
+- If there is something special required to run the local server or there is an extra flag that should always be set
+  like `AUTH`, add that logic to `.evergreen/scripts/run_server.py`.
+- The bulk of the logic will typically be in `.evergreen/scripts/setup_tests.py`.  This is where you should fetch secrets and make them available using `write_env`, start services, and write other env vars needed using `write_env`.
+- If there are any special test considerations, including not running `pytest` at all, handle it in `.evergreen/scripts/run_tests.py`.
+- If there are any services or atlas clusters to teardown, handle them in `.evergreen/scripts/teardown_tests.py`.
+- Add functions to generate the test variant(s) and task(s) to the `.evergreen/scripts/generate_config.py`.
+- There are some considerations about the Python version used in the test:
+    - If a specific version of Python is needed in a task that is running on variants with a toolchain, use
+``TOOLCHAIN_VERSION`` (e.g. `TOOLCHAIN_VERSION=3.10`).  The actual path lookup needs to be done on the host, since
+tasks are host-agnostic.
+    - If a specific Python binary is needed (for example on the FIPS host), set `UV_PYTHON=/path/to/python`.
+    - If a specific Python version is needed and the toolchain will not be available, use `UV_PYTHON` (e.g. `UV_PYTHON=3.11`).
+    - The default if neither ``TOOLCHAIN_VERSION`` or ``UV_PYTHON`` is set is to use UV to install the minimum
+      supported version of Python and use that.  This ensures a consistent behavior across host types that do not
+      have the Python toolchain (e.g. Azure VMs), by having a known version of Python with the build headers (`Python.h`)
+      needed to build the C extensions.
+- Regenerate the test variants and tasks using `pre-commit run --all-files generate-config`.
+- Make sure to add instructions for running the test suite to `CONTRIBUTING.md`.
+
+## Handling flaky tests
+
+We have a custom `flaky` decorator in [test/asynchronous/utils.py](test/asynchronous/utils.py) that can be used for
+tests that are `flaky`.  By default the decorator only applies when not running on CPython on Linux, since other
+runtimes tend to have more variation.  When using the `flaky` decorator, open a corresponding ticket and
+a use the ticket number as the "reason" parameter to the decorator, e.g. `@flaky(reason="PYTHON-1234")`.
+When running tests locally (not in CI), the `flaky` decorator will be disabled unless `ENABLE_FLAKY` is set.
+To disable the `flaky` decorator in CI, you can use `evergreen patch --param DISABLE_FLAKY=1`.
+
+## Integration Tests
+
+The `integration_tests` directory has a set of scripts that verify the usage of PyMongo with downstream packages or frameworks.  See the [README](./integration_tests/README.md) for more information.
+
+To run the tests, use `just integration_tests`.
+
+The tests should be able to run with and without SSL enabled.
+
+## Specification Tests
+
+The MongoDB [specifications repository](https://github.com/mongodb/specifications)
+holds in progress and completed specifications for features of MongoDB, drivers,
+and associated products. PyMongo supports the [Unified Test Format](https://jira.mongodb.org/browse/DRIVERS-709)
+for running specification tests to confirm PyMongo behaves as expected.
+
+### Resynchronizing the Specification Tests
+
+If you would like to re-sync the copy of the specification tests in the
+PyMongo repository with that which is inside the [specifications
+repo](https://github.com/mongodb/specifications), please use the script
+provided in `.evergreen/resync-specs.sh`.:
+
+```bash
+git clone git@github.com:mongodb/specifications.git
+export MDB_SPECS=~/specifications
+cd ~/mongo-python-driver/.evergreen
+./resync-specs.sh -b "<regex>" spec1 spec2 ...
+./resync-specs.sh -b "connection-string*" crud bson-corpus # Updates crud and bson-corpus specs while ignoring all files with the regex "connection-string*"
+cd ..
+```
+
+The `-b` flag adds as a regex pattern to block files you do not wish to
+update in PyMongo. This is primarily helpful if you are implementing a
+new feature in PyMongo that has spec tests already implemented, or if
+you are attempting to validate new spec tests in PyMongo.
+
+### Automated Specification Test Resyncing
+The (`/.evergreen/scripts/resync-all-specs.sh`) script
+automatically runs once a week to resync all the specs with the [specifications repo](https://github.com/mongodb/specifications).
+A PR will be generated by mongodb-drivers-pr-bot containing any changes picked up by this resync.
+The PR description will display the name(s) of the updated specs along
+with any errors that occurred.
+
+Spec test changes associated with a behavioral change or bugfix that has yet to be implemented in PyMongo
+must be added to a patch file in `/.evergreen/spec-patch`. Each patch
+file must be named after the associated PYTHON ticket and contain the
+test differences between PyMongo's current tests and the specification.
+All changes listed in these patch files will be *undone* by the script and won't
+be applied to PyMongo's tests.
+
+When a new test file or folder is added to the spec repo before the associated code changes are implemented, that test's path must be added to  `.evergreen/remove-unimplemented-tests.sh` along with a comment indicating the associated PYTHON ticket for those changes.
+
+Any PR that implements a PYTHON ticket documented in a patch file or within  `.evergreen/remove-unimplemented-tests.sh` must also remove the associated patch file or entry in `remove-unimplemented-tests.sh`.
+
+#### Adding to a patch file
+To add to or create a patch file, run `git diff` to show the desired changes to undo and copy the
+results into the patch file.
+
+For example: the imaginary, unimplemented PYTHON-1234 ticket has associated spec test changes. To add those changes to `PYTHON-1234.patch`), do the following:
+```bash
+git diff HEAD~1 path/to/file >> .evergreen/spec-patch/PYTHON-1234.patch
+```
+
+#### Running Locally
+Both `resync-all-specs.sh` and `resync-all-specs.py` can be run locally (and won't generate a PR).
+```bash
+./.evergreen/scripts/resync-all-specs.sh
+python3 ./.evergreen/scripts/resync-all-specs.py
+```
+
+## Making a Release
+
+Follow the [Python Driver Release Process Wiki](https://wiki.corp.mongodb.com/display/DRIVERS/Python+Driver+Release+Process).
+
+## Project Structure and Asyncio Considerations
+
+This section describes the layout of the `pymongo/` package.
+
+Within `pymongo/`, the code is further divided into the `pymongo/asynchronous` and `pymongo/synchronous` subdirectories.
+Files in `pymongo/synchronous` are generated from `pymongo/asynchronous` using the `synchro` pre-commit hook, which uses [unasync](https://github.com/python-trio/unasync/) and some custom transforms.
+
+As a result, **all modifications** within `pymongo` must be made in either the top-level `pymongo` directory when they have to exhibit differing behavior between sync and async contexts or the `pymongo/asynchronous` directory, not `pymongo/synchronous`.
+Any changes made directly to files in the `pymongo/synchronous` directory will be overwritten by the `synchro` hook when it is run, which happens automatically on commit.
+
+Some top-level files (e.g. `pymongo/collection.py`) are re-export files for existing import compatibility and should not be modified directly.
+The other top-level files (e.g. `pymongo/network_layer.py`, `pymongo/pool_shared.py`) contain either shared code used in both the asynchronous and synchronous APIs, or code that is very different between the two APIs and therefore cannot be generated from the async version using `synchro`.
+
+Run `pre-commit run --all-files synchro` before running tests to generate the latest version of the synchronous code.
+
+To prevent the `synchro` hook from accidentally overwriting code, it first checks to see whether a sync version
+of a file is changing and not its async counterpart, and will fail.
+In the unlikely scenario that you want to override this behavior, first export `OVERRIDE_SYNCHRO_CHECK=1`.
+
+Sometimes, the `synchro` hook will fail and introduce changes many previously unmodified files. This is due to static
+Python errors, such as missing imports, incorrect syntax, or other fatal typos. To resolve these issues,
+run `pre-commit run --all-files --hook-stage manual ruff` and fix all reported errors before running the `synchro`
+hook again.
+
+## Converting a test to async
+
+The `tools/convert_test_to_async.py` script takes in an existing synchronous test file and outputs a
+partially-converted asynchronous version of the same name to the `test/asynchronous` directory.
+Use this generated file as a starting point for the completed conversion.
+
+The script is used like so: `python tools/convert_test_to_async.py [test_file.py]`
+
+## CPU profiling
+
+To profile a test script and generate a flame graph, follow these steps:
+
+1. Install `py-spy` if you haven't already:
+   ```bash
+   pip install py-spy
+   ```
+2. Inside your test script, perform any required setup and then loop over the code you want to profile for improved sampling.
+3. Run `py-spy record -o <output.svg> -r <sample_rate=100> -- python <path/to/script>` to generate a `.svg` file containing the flame graph.
+   (Note: on macOS you will need to run this command using `sudo` to allow `py-spy` to attach to the Python process.)
+4. If you need to include native code (for example the C extensions), profiling should be done on a Linux system, as macOS and Windows do not support the `--native` option of `py-spy`.
+   Creating an ubuntu Evergreen spawn host and using `scp` to copy the flamegraph `.svg` file back to your local machine is the best way to do this.
+5. You can then view the flamegraph using an SVG viewer like a browser.
+
+## Memory profiling
+
+To test for a memory leak or any memory-related issues, the current best tool is [memray](https://bloomberg.github.io/memray/overview.html).
+In order to include code from our C extensions, it must be run in native mode, on Linux.
+To do so, either spin up an Ubuntu docker container or an Ubuntu Evergreen spawn host.
+
+From the spawn host or Ubuntu image, do the following:
+
+1. Install `memray` if you haven't already:
+   ```bash
+   pip install memray
+   ```
+2. Inside your test script, perform any required setup and then loop over the code you want to profile for improved sampling.
+3. Run memray with the script under test with the `--native` flag, e.g. `python -m memray run --native -o test.bin <path/to/script>`.
+4. Generate the flamegraph with `python -m memray flamegraph -o test.html test.bin`.
+   See the [docs](https://bloomberg.github.io/memray/flamegraph.html) for more options.
+5. Then, from the host computer, use either scp or docker cp to copy the flamegraph, e.g. `scp ubuntu@ec2-3-82-52-49.compute-1.amazonaws.com:/home/ubuntu/test.html .`.
+6. You can then view the flamegraph html in a browser.
+
+## Dependabot updates
+
+Dependabot will raise PRs at most once per week, grouped by GitHub Actions updates and Python requirement
+file updates.  We have a pre-commit hook that will update the `uv.lock` file when requirements change.
+To update the lock file on a failing PR, you can use a method like `gh pr checkout <pr number>`, then run
+`just lint uv-lock` to update the lock file, and then push the changes.  If a typing dependency has changed,
+also run `just typing` and handle any new findings.

-Contributing to PyMongo
-=======================
-
-PyMongo has a large `community
-<https://pymongo.readthedocs.io/en/stable/contributors.html>`_ and
-contributions are always encouraged. Contributions can be as simple as
-minor tweaks to the documentation. Please read these guidelines before
-sending a pull request.
-
-Bugfixes and New Features
--------------------------
-
-Before starting to write code, look for existing `tickets
-<https://jira.mongodb.org/browse/PYTHON>`_ or `create one
-<https://jira.mongodb.org/browse/PYTHON>`_ for your specific
-issue or feature request. That way you avoid working on something
-that might not be of interest or that has already been addressed.
-
-Supported Interpreters
-----------------------
-
-PyMongo supports CPython 3.7+ and PyPy3.7+. Language
-features not supported by all interpreters can not be used.
-
-Style Guide
------------
-
-PyMongo follows `PEP8 <http://www.python.org/dev/peps/pep-0008/>`_
-including 4 space indents and 79 character line limits.
-
-General Guidelines
-------------------
-
-- Avoid backward breaking changes if at all possible.
-- Write inline documentation for new classes and methods.
-- Write tests and make sure they pass (make sure you have a mongod
-  running on the default port, then execute ``python setup.py test``
-  from the cmd line to run the test suite).
-- Add yourself to doc/contributors.rst :)
-
-Running Linters
----------------
-
-PyMongo uses `pre-commit <https://pypi.org/project/pre-commit/>`_
-for managing linting of the codebase.
-``pre-commit`` performs various checks on all files in PyMongo and uses tools
-that help follow a consistent code style within the codebase.
-
-To set up ``pre-commit`` locally, run::
-
-    pip install pre-commit
-    pre-commit install
-
-To run ``pre-commit`` manually, run::
-
-    pre-commit run --all-files
-
-To run a manual hook like `flake8` manually, run::
-
-    pre-commit run --all-files --hook-stage manual flake8
-
-Documentation
--------------
-
-To contribute to the `API documentation <https://pymongo.readthedocs.io/en/stable/>`_
-just make your changes to the inline documentation of the appropriate
-`source code <https://github.com/mongodb/mongo-python-driver>`_ or `rst file
-<https://github.com/mongodb/mongo-python-driver/tree/master/doc>`_ in a
-branch and submit a `pull request <https://help.github.com/articles/using-pull-requests>`_.
-You might also use the GitHub `Edit <https://github.com/blog/844-forking-with-the-edit-button>`_
-button.
-
-Running Tests Locally
----------------------
-- Ensure you have started the appropriate Mongo Server(s).
-- Run ``python setup.py test`` to run all of the tests.
-- Run ``python setup.py test -s test.<mod_name>.<class_name>.<test_name>`` to
-  run specific tests.  You can omit the ``<test_name>`` to test a full class
-  and the ``<class_name>`` to test a full module.  For example:
-  ``python setup.py test -s test.test_change_stream.TestUnifiedChangeStreamsErrors.test_change_stream_errors_on_ElectionInProgress``.
-
-Running Load Balancer Tests Locally
------------------------------------
-- Install ``haproxy`` (available as ``brew install haproxy`` on macOS).
-- Clone ``drivers-evergreen-tools``: ``git clone git@github.com:mongodb-labs/drivers-evergreen-tools.git``.
-- Start the servers using ``LOAD_BALANCER=true TOPOLOGY=sharded_cluster AUTH=noauth SSL=nossl MONGODB_VERSION=6.0 DRIVERS_TOOLS=$PWD/drivers-evergreen-tools MONGO_ORCHESTRATION_HOME=$PWD/drivers-evergreen-tools/.evergreen/orchestration $PWD/drivers-evergreen-tools/.evergreen/run-orchestration.sh``.
-- Start the load balancer using: ``MONGODB_URI='mongodb://localhost:27017,localhost:27018/' $PWD/drivers-evergreen-tools/.evergreen/run-load-balancer.sh start``.
-- Run the tests from the ``pymongo`` checkout directory using: ``LOADBALANCER=1 TEST_LOADBALANCER=1 SINGLE_MONGOS_LB_URI='mongodb://127.0.0.1:8000/?loadBalanced=true' MULTI_MONGOS_LB_URI='mongodb://127.0.0.1:8001/?loadBalanced=true' MONGODB_URI='mongodb://localhost:27017,localhost:27018/' python setup.py test -s test.test_load_balancer``.
-
-Re-sync Spec Tests
-------------------
-
-If you would like to re-sync the copy of the specification tests in the
-PyMongo repository with that which is inside the `specifications repo
-<https://github.com/mongodb/specifications>`_, please
-use the script provided in ``.evergreen/resync-specs.sh``.::
-
-    git clone git@github.com:mongodb/specifications.git
-    export MDB_SPECS=~/specifications
-    cd ~/mongo-python-driver/.evergreen
-    ./resync-specs.sh -b "connection-string*" crud bson-corpus
-    cd ..
-
-The ``-b`` flag adds as a regex pattern to block files you do not wish to
-update in PyMongo.
-This is primarily helpful if you are implementing a new feature in PyMongo
-that has spec tests already implemented, or if you are attempting to
-validate new spec tests in PyMongo.

+## About
+
+The PyMongo distribution contains tools for interacting with MongoDB
+database from Python. The `bson` package is an implementation of the
+[BSON format](http://bsonspec.org) for Python. The `pymongo` package is
+a native Python driver for MongoDB, offering both synchronous and asynchronous APIs. The `gridfs` package is a
+[gridfs](https://github.com/mongodb/specifications/blob/master/source/gridfs/gridfs-spec.md/)
+implementation on top of `pymongo`.
+
+PyMongo supports MongoDB 4.0, 4.2, 4.4, 5.0, 6.0, 7.0, and 8.0. PyMongo follows [semantic versioning](https://semver.org/spec/v2.0.0.html) for its releases.
+
+## Documentation
+
+Documentation is available at
+[mongodb.com](https://www.mongodb.com/docs/languages/python/pymongo-driver/current/).
+
+[API documentation](https://pymongo.readthedocs.io/en/stable/api/) and the [full changelog](https://pymongo.readthedocs.io/en/stable/changelog.html) for each release is available at [readthedocs.io](https://pymongo.readthedocs.io/en/stable/index.html).
+
+## Support / Feedback
+
+For issues with, questions about, or feedback for PyMongo, please look
+into our [support channels](https://support.mongodb.com/welcome). Please
+do not email any of the PyMongo developers directly with issues or
+questions - you're more likely to get an answer on
+[StackOverflow](https://stackoverflow.com/questions/tagged/mongodb)
+(using a "mongodb" tag).
+
+## Bugs / Feature Requests
+
+Think you've found a bug? Want to see a new feature in PyMongo? Please
+open a case in our issue management tool, JIRA:
+
+-   [Create an account and login](https://jira.mongodb.org).
+-   Navigate to [the PYTHON
+    project](https://jira.mongodb.org/browse/PYTHON).
+-   Click **Create Issue** - Please provide as much information as
+    possible about the issue type and how to reproduce it.
+
+Bug reports in JIRA for all driver projects (i.e. PYTHON, CSHARP, JAVA)
+and the Core Server (i.e. SERVER) project are **public**.
+
+### How To Ask For Help
+
+Please include all of the following information when opening an issue:
+
+-   Detailed steps to reproduce the problem, including full traceback,
+    if possible.
+
+-   The exact python version used, with patch level:
+
+```bash
+python -c "import sys; print(sys.version)"
+```
+
+-   The exact version of PyMongo used, with patch level:
+
+```bash
+python -c "import pymongo; print(pymongo.version); print(pymongo.has_c())"
+```
+
+-   The operating system and version (e.g. Windows 7, OSX 10.8, ...)
+
+-   Web framework or asynchronous network library used, if any, with
+    version (e.g. Django 1.7, mod_wsgi 4.3.0, gevent 1.0.1, Tornado
+    4.0.2, ...)
+
+### Security Vulnerabilities
+
+If you've identified a security vulnerability in a driver or any other
+MongoDB project, please report it according to the [instructions
+here](https://www.mongodb.com/docs/manual/tutorial/create-a-vulnerability-report/).
+
+## Installation
+
+PyMongo can be installed with [pip](http://pypi.python.org/pypi/pip):
+
+```bash
+python -m pip install pymongo
+```
+
+You can also download the project source and do:
+
+```bash
+pip install .
+```
+
+Do **not** install the "bson" package from pypi. PyMongo comes with
+its own bson package; running "pip install bson" installs a third-party
+package that is incompatible with PyMongo.
+
+## Dependencies
+
+PyMongo supports CPython 3.9+ and PyPy3.9+.
+
+Required dependencies:
+
+Support for `mongodb+srv://` URIs requires [dnspython](https://pypi.python.org/pypi/dnspython)
+
+Optional dependencies:
+
+GSSAPI authentication requires
+[pykerberos](https://pypi.python.org/pypi/pykerberos) on Unix or
+[WinKerberos](https://pypi.python.org/pypi/winkerberos) on Windows. The
+correct dependency can be installed automatically along with PyMongo:
+
+```bash
+python -m pip install "pymongo[gssapi]"
+```
+
+MONGODB-AWS authentication requires
+[pymongo-auth-aws](https://pypi.org/project/pymongo-auth-aws/):
+
+```bash
+python -m pip install "pymongo[aws]"
+```
+
+OCSP (Online Certificate Status Protocol) requires
+[PyOpenSSL](https://pypi.org/project/pyOpenSSL/),
+[requests](https://pypi.org/project/requests/),
+[service_identity](https://pypi.org/project/service_identity/) and may
+require [certifi](https://pypi.python.org/pypi/certifi):
+
+```bash
+python -m pip install "pymongo[ocsp]"
+```
+
+Wire protocol compression with snappy requires
+[python-snappy](https://pypi.org/project/python-snappy):
+
+```bash
+python -m pip install "pymongo[snappy]"
+```
+
+Wire protocol compression with zstandard requires
+[backports.zstd](https://pypi.org/project/backports.zstd)
+when used with Python versions before 3.14:
+
+```bash
+python -m pip install "pymongo[zstd]"
+```
+
+Client-Side Field Level Encryption requires
+[pymongocrypt](https://pypi.org/project/pymongocrypt/) and
+[pymongo-auth-aws](https://pypi.org/project/pymongo-auth-aws/):
+
+```bash
+python -m pip install "pymongo[encryption]"
+```
+You can install all dependencies automatically with the following
+command:
+
+```bash
+python -m pip install "pymongo[gssapi,aws,ocsp,snappy,zstd,encryption]"
+```
+
+## Examples
+
+Here's a basic example (for more see the *examples* section of the
+docs):
+
+```pycon
+>>> import pymongo
+>>> client = pymongo.MongoClient("localhost", 27017)
+>>> db = client.test
+>>> db.name
+'test'
+>>> db.my_collection
+Collection(Database(MongoClient('localhost', 27017), 'test'), 'my_collection')
+>>> db.my_collection.insert_one({"x": 10}).inserted_id
+ObjectId('4aba15ebe23f6b53b0000000')
+>>> db.my_collection.insert_one({"x": 8}).inserted_id
+ObjectId('4aba160ee23f6b543e000000')
+>>> db.my_collection.insert_one({"x": 11}).inserted_id
+ObjectId('4aba160ee23f6b543e000002')
+>>> db.my_collection.find_one()
+{'x': 10, '_id': ObjectId('4aba15ebe23f6b53b0000000')}
+>>> for item in db.my_collection.find():
+...     print(item["x"])
+...
+10
+8
+11
+>>> db.my_collection.create_index("x")
+'x_1'
+>>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):
+...     print(item["x"])
+...
+8
+10
+11
+>>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)]
+[8, 11]
+```

-About
-=====
-
-The PyMongo distribution contains tools for interacting with MongoDB
-database from Python.  The ``bson`` package is an implementation of
-the `BSON format <http://bsonspec.org>`_ for Python. The ``pymongo``
-package is a native Python driver for MongoDB. The ``gridfs`` package
-is a `gridfs
-<https://github.com/mongodb/specifications/blob/master/source/gridfs/gridfs-spec.rst/>`_
-implementation on top of ``pymongo``.
-
-PyMongo supports MongoDB 3.6, 4.0, 4.2, 4.4, 5.0, and 6.0.
-

-Security Vulnerabilities
-------------------------
-
-If you’ve identified a security vulnerability in a driver or any other
-MongoDB project, please report it according to the `instructions here
-<https://www.mongodb.com/docs/manual/tutorial/create-a-vulnerability-report/>`_.
-
-Installation
-============
-
-PyMongo can be installed with `pip <http://pypi.python.org/pypi/pip>`_::
-
-  $ python -m pip install pymongo
-
-Or ``easy_install`` from
-`setuptools <http://pypi.python.org/pypi/setuptools>`_::
-
-  $ python -m easy_install pymongo
-
-You can also download the project source and do::
-
-  $ python setup.py install
-
-Do **not** install the "bson" package from pypi. PyMongo comes with its own
-bson package; doing "easy_install bson" installs a third-party package that
-is incompatible with PyMongo.
-
-Dependencies
-============
-
-PyMongo supports CPython 3.7+ and PyPy3.7+.
-
-Required dependencies:
-
-Support for mongodb+srv:// URIs requires `dnspython
-<https://pypi.python.org/pypi/dnspython>`_
-
-Optional dependencies:
-
-GSSAPI authentication requires `pykerberos
-<https://pypi.python.org/pypi/pykerberos>`_ on Unix or `WinKerberos
-<https://pypi.python.org/pypi/winkerberos>`_ on Windows. The correct
-dependency can be installed automatically along with PyMongo::
-
-  $ python -m pip install "pymongo[gssapi]"
-
-MONGODB-AWS authentication requires `pymongo-auth-aws
-<https://pypi.org/project/pymongo-auth-aws/>`_::
-
-  $ python -m pip install "pymongo[aws]"
-
-
-OCSP (Online Certificate Status Protocol) requires `PyOpenSSL
-<https://pypi.org/project/pyOpenSSL/>`_, `requests
-<https://pypi.org/project/requests/>`_, `service_identity
-<https://pypi.org/project/service_identity/>`_ and may
-require `certifi
-<https://pypi.python.org/pypi/certifi>`_::
-
-  $ python -m pip install "pymongo[ocsp]"
-
-Wire protocol compression with snappy requires `python-snappy
-<https://pypi.org/project/python-snappy>`_::
-
-  $ python -m pip install "pymongo[snappy]"
-
-Wire protocol compression with zstandard requires `zstandard
-<https://pypi.org/project/zstandard>`_::
-
-  $ python -m pip install "pymongo[zstd]"
-
-Client-Side Field Level Encryption requires `pymongocrypt
-<https://pypi.org/project/pymongocrypt/>`_ and
-`pymongo-auth-aws <https://pypi.org/project/pymongo-auth-aws/>`_::
-
-  $ python -m pip install "pymongo[encryption]"
-
-You can install all dependencies automatically with the following
-command::
-
-  $ python -m pip install "pymongo[gssapi,aws,ocsp,snappy,zstd,encryption]"
-
-Additional dependencies are:

-
-Examples
-========
-Here's a basic example (for more see the *examples* section of the docs):
-
-.. code-block:: python
-
-  >>> import pymongo
-  >>> client = pymongo.MongoClient("localhost", 27017)
-  >>> db = client.test
-  >>> db.name
-  'test'
-  >>> db.my_collection
-  Collection(Database(MongoClient('localhost', 27017), 'test'), 'my_collection')
-  >>> db.my_collection.insert_one({"x": 10}).inserted_id
-  ObjectId('4aba15ebe23f6b53b0000000')
-  >>> db.my_collection.insert_one({"x": 8}).inserted_id
-  ObjectId('4aba160ee23f6b543e000000')
-  >>> db.my_collection.insert_one({"x": 11}).inserted_id
-  ObjectId('4aba160ee23f6b543e000002')
-  >>> db.my_collection.find_one()
-  {'x': 10, '_id': ObjectId('4aba15ebe23f6b53b0000000')}
-  >>> for item in db.my_collection.find():
-  ...     print(item["x"])
-  ...
-  10
-  8
-  11
-  >>> db.my_collection.create_index("x")
-  'x_1'
-  >>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):
-  ...     print(item["x"])
-  ...
-  8
-  10
-  11
-  >>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)]
-  [8, 11]
-
-Documentation
-=============
-
-Documentation is available at `pymongo.readthedocs.io <https://pymongo.readthedocs.io/en/stable/>`_.
-
-To build the documentation, you will need to install sphinx_.
-Documentation can be generated by running **python
-setup.py doc**. Generated documentation can be found in the
-*doc/build/html/* directory.
-
-Testing
-=======
-
-The easiest way to run the tests is to run **python setup.py test** in
-the root of the distribution.
-
-To verify that PyMongo works with Gevent's monkey-patching::
-
-    $ python green_framework_test.py gevent
-
-Or with Eventlet's::
-
-    $ python green_framework_test.py eventlet

-Some notes on PyMongo releases
-==============================
-
-Versioning
-----------
-
-We shoot for a release every few months - that will generally just
-increment the middle / minor version number (e.g. 3.5.0 -> 3.6.0).
-
-Patch releases are reserved for bug fixes (in general no new features
-or deprecations) - they only happen in cases where there is a critical
-bug in a recently released version, or when a release has no new
-features or API changes.
-
-In between releases we add .devN to the version number to denote the version
-under development. So if we just released 3.6.0, then the current dev
-version might be 3.6.1.dev0 or 3.7.0.dev0. When we make the next release we
-replace all instances of 3.x.x.devN in the docs with the new version number.
-
-https://semver.org/
-https://www.python.org/dev/peps/pep-0440/
-
-Deprecation
------------
-
-Changes should be backwards compatible unless absolutely necessary. When making
-API changes the approach is generally to add a deprecation warning but keeping
-the existing API functional. Deprecated features can be removed in a release
-that changes the major version number.
-
-Doing a Release
----------------
-
-1. PyMongo is tested on Evergreen. Ensure the latest commit are passing CI
-   as expected: https://evergreen.mongodb.com/waterfall/mongo-python-driver.
-   To test locally, ``python3 setup.py test`` will build the C extensions and
-   test. ``python3 tools/clean.py`` will remove the extensions,
-   and then ``python3 setup.py --no_ext test`` will run the tests without
-   them. You can also run the doctests: ``python3 setup.py doc -t``.
-
-2. Check Jira to ensure all the tickets in this version have been completed.
-
-3. Add release notes to doc/changelog.rst. Generally just summarize/clarify
-   the git log, but you might add some more long form notes for big changes.
-
-4. Make sure version number is updated in ``pymongo/_version.py``
-
-5. Commit with a BUMP version_number message, eg ``git commit -m 'BUMP 3.11.0'``.
-
-6. Tag w/ version_number, eg, ``git tag -a '3.11.0' -m 'BUMP 3.11.0' <COMMIT>``.
-
-7. Push commit / tag, eg ``git push && git push --tags``.
-
-8. Pushing a tag will trigger a release process in Evergreen which builds
-   wheels for manylinux, macOS, and Windows. Wait for the "release-combine"
-   task to complete and then download the "Release files all" archive. See:
-   https://evergreen.mongodb.com/waterfall/mongo-python-driver?bv_filter=release
-
-   The contents should look like this::
-
-     $ ls path/to/archive
-     pymongo-<version>-cp310-cp310-macosx_10_9_universal2.whl
-     ...
-     pymongo-<version>-cp38-cp38-manylinux2014_x86_64.whl
-     ...
-     pymongo-<version>-cp38-cp38-win_amd64.whl
-     ...
-     pymongo-<version>.tar.gz
-
-9. Upload all the release packages to PyPI with twine::
-
-     $ python3 -m twine upload path/to/archive/*
-
-10. Make sure the new version appears on https://pymongo.readthedocs.io/. If the
-    new version does not show up automatically, trigger a rebuild of "latest":
-    https://readthedocs.org/projects/pymongo/builds/
-
-11. Bump the version number to <next version>.dev0 in ``pymongo/_version.py``,
-    commit, push.
-
-12. Publish the release version in Jira.
-
-13. Announce the release on:
-    https://www.mongodb.com/community/forums/c/announcements/driver-releases/110
-
-14. File a ticket for DOCSP highlighting changes in server version and Python
-    version compatibility or the lack thereof, for example:
-    https://jira.mongodb.org/browse/DOCSP-13536
-
-15. Create a GitHub Release for the tag using
-    https://github.com/mongodb/mongo-python-driver/releases/new.
-    The title should be "PyMongo X.Y.Z", and the description should contain
-    a link to the release notes on the the community forum, e.g.
-    "Release notes: mongodb.com/community/forums/t/pymongo-4-0-2-released/150457."
