Where should I add documentation for pre-commit? To main READ.ME?
I used python to install pre-commit as it is the easies way to install it on every OS. Is this way OK?

Add some markdown file in docs directory.

I need anyway to completely rework the README files, once that is done I will link it there.

.pre-commit-config.yaml:1

• [nitpick] We should update the README to include instructions for developers to run pre-commit install after cloning, ensuring the hooks are activated locally.

repos:

.clang-format:1

• [nitpick] It may help to add a comment or contributor guide explaining any deviations from the base Google style (e.g., pointer alignment), so new contributors understand these rules.
