Create AI Policy

The motivation for adopting this policy is to avoid wasting the maintainers'
time. We work on this project as volunteers and it is an unproductive waste of
time to interact with contributors who do not understand their contributions.

While we generaly would prefer to receive contributions which are not AI
generated, we understand that such tools can provide value in limited ways.
Therefore, we have attempted to create a policy which allows use of such tools
while also holding the contributor accountable. Hopefully this accomplishes our
goal. Closes #1610.

+## AI Contributions
+
+Contributions to the Python-Markdown project are welcome, including those
+developed with the assistance of generative AI tools. However, the use of
+such tools does not change expectations for contributor responsibility,
+engagement, or code quality. The following apply to all contributions.
+
+Contributors are responsible for all submitted content, regardless of whether
+generative AI tools were used.
+
+Contributors must be able to explain all changes upon request during review.
+
+Contributors are responsible for ensuring all submitted code complies with
+Python-Markdown's licensing, regardless of whether generative AI tools were
+used.
+
+The pull request process should be collaborative and iterative. Contributors
+are expected to actively engage with reviewer feedback themselves.
+Contributors are expected to understand the changes they are proposing, not
+act as a message courier for a third party. Copying and pasting replies to /
+from a generative AI tool does not count as engaging with the reviewer. The
+use of an AI agent to submit a pull request, issue, or comment autonomously
+is not permitted.
+
+All code and prose (documentation, commit messages, comments, etc.) must
+reflect the style and conventions used by the Python-Markdown project (see
+[Code Style Guide](#code-style-guide), [Documentation Style
+Guide](#documentation-style-guide), and [Commit Message Style
+Guide](#commit-message-style-guide) below).
+
+Maintainers may close issues and pull requests that are not useful or
+productive, regardless of whether AI tools were used or not. If a contributor
+repeatedly opens unproductive issues or requests, they may be blocked from
+contributing to the project as it is disruptive and disrespectful of the
+maintainers' time.
+
+!!! Note
+    This policy was largely inspired by the Astropy Project's 
+    [Usage of Generative AI] policy.
