-I am happy that you want to contribute to Pocket ID and help to make it better! All contributions are welcome, including issues, suggestions, pull requests and more.
+We are happy that you want to contribute to Pocket ID and help to make it better!
+
+## Before you start
+
+Before starting to work on a new feature, please open an issue first, or comment on an existing one, to discuss the implementation details. This saves you time and avoids the disappointment of having a PR closed later because the change doesn't fit the project's direction.
+
+### AI Usage Policy
+
+We have nothing against using AI tools to assist your development. But we've seen a growing number of pull requests that appear to be fully or largely AI-generated and submitted without genuine human review. These are difficult and time-consuming for maintainers to review, and they often waste everyone's time.
+
+To keep contributions reviewable and high-quality, please follow these guidelines when using AI tools.
+
+#### Guidelines for Using AI Tools
+
+1. **Understand every line.** You must be able to explain what your code does and why, in your own words. "The AI wrote it" is not an acceptable answer to a reviewer's question.
+2. **Test before submitting.** Review and test all code manually, as a human, before opening a PR. Don't trust the AI's claim that it works.
+3. **Write your own words.** Don't paste AI-generated text into issues, comments, or PR descriptions. Walls of generated text make discussions harder, not easier.
+4. **Disclose your usage.** Note in the PR description how you used AI (see below).
+
+PRs that appear to be low effort AI output may be closed without a detailed review.
+
+#### Example disclosure
+
+> Used GitHub Copilot for autocomplete, and asked an LLM to help draft the test cases in `parser_test.go`. I reviewed, edited, and tested everything myself and understand how it works.
+
+> Used an LLM to generate the initial implementation of the new API endpoint, but I manually reviewed and tested it before submitting.
