+## Issue Management

+- **Closing Issues:** When a commit fixes or closes an issue, the commit message must include a supported keyword followed by the issue number (e.g., `fixes #123`, `closes #456`).
+  - Supported keywords: `close`, `closes`, `closed`, `fix`, `fixes`, `fixed`, `resolve`, `resolves`, `resolved`.
+  - **Placement:** This pattern should always be placed at the very end of the commit body (not the subject line).
+
+## PRs
+
+Do create PRs only on a specific user request. Do not create them on your own initiative.
+A PR should always contain a note if an issue is closed with it.
