-# Contribution Rules/Coding Standards
-No need to throw away your coding style, just do your best to follow default clang-format style.
-Apply `clang-format` to the source files before commit:
-```sh
-for file in $(git ls-files | \grep -E '\.(c|h)$' | \grep -v -- '#')
-do
-    clang-format -i $file
-done
