+# Contributing to Django MongoDB Backend
+
+Django MongoDB Backend welcomes contributions from any developer. Contributions
+can take the form of bug fixes, feature requests, or issue tickets.
+
+- **Issue tickets** can be submitted via
+  [GitHub issues](https://github.com/django-mongodb/django-mongodb-backend/issues).
+- **Bug fixes** can be submitted directly as pull requests.
+- **Large code changes** should be preceded by an issue ticket filed with the
+  team to align on approach before implementation begins.
+
+For full contributing guidelines — including coding style, testing
+requirements, documentation standards, and our AI-generated contributions
+policy, see the [contributing documentation](https://django-mongodb-backend.readthedocs.io/en/latest/internals/contributing/).

+================================
+AI-Generated Contribution 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**: Django MongoDB Backend bridges Django's ORM and
+  MongoDB. The aggregation pipeline compilation, query generation, migration
+  system, and connection management 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**: Query generation, authentication handling, and
+  data serialization cannot be left to probabilistic code generation.
+
+What This Means for Contributors
+---------------------------------
+
+**Required:**
+
+- A full understanding of every line of code you submit.
+- The ability to explain and defend your implementation choices.
+- A 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 their development process.
+
+Questions?
+----------
+
+If you're unsure whether your contribution complies with this policy, please
+ask for guidance within the PR and clarify any uncertainty. We're happy to
+guide contributors toward successful contributions.
+
+.. note::
+
+   This policy helps us maintain the reliability, security, and trustworthiness
+   that production applications depend on. Thank you for understanding and for
+   contributing thoughtfully to Django MongoDB Backend.
