 Before preparing or proposing a commit, you **must** run the entire local test suite and ensure that all tests pass. This is a critical step to prevent regressions and maintain the stability of the codebase.
 
 Refer to the "Testing" section in `HOWTO.md` for instructions on how to build and run the tests.

+### Format Code Before Committing
+
+All code **must** be formatted using `clang-format` before committing. This ensures a consistent coding style across the entire codebase.
+
+To format your code, run the following command from the project root:
+```bash
+clang-format -i $(git ls-files | grep -E '\.(h|cc)$')
+```
+
+Refer to the `.clang-format` file in the project root for the specific style rules.
