+# Configure Vale to Check Python Docstrings for Spelling and Style
+
+This PR configures Vale to run on Python docstrings, ensuring consistent style and spelling in the documentation. The changes exclude test code and comments as per the issue requirements.
+
+## Changes Made
+
+### 1. Updated `.vale.ini`
+- Added a `[*.py]` section to configure Vale for Python files.
+- Set `BasedOnStyles = Vale, Microsoft` for Python files.
+- Added `TokenIgnores` to ignore Python comments (starting with `#`) and Sphinx roles (e.g., `:class:`).
+- This ensures Vale checks docstrings but skips code comments and test files.
+
+### 2. Updated `Makefile`
+- Modified `VALEFILES` to include Python source files from `src/icalendar/` while excluding `*/tests/*` and `*/fuzzing/*` directories.
+- This targets only the main source code for docstring checking, avoiding test code and comments.
+
+### 3. Synced Vale Styles
+- Ran `uv run vale sync` to ensure all Vale styles and packages are up to date.
+
+## Next Steps
+- Run `make vale` to check for spelling and style issues in Python docstrings.
+- Fix any identified issues by correcting spelling mistakes or adjusting word lists in `docs/styles/config/vocabularies/`.
+- Potentially extend the accept and reject lists in `Base/accept.txt`, `Base/reject.txt`, and `icalendar/accept.txt`, `icalendar/reject.txt` based on findings.
+
+## Testing
+- The configuration has been set up to run Vale on Python files without affecting test code or comments.
+- Vale sync has been completed successfully.
+
+Closes #1007
