 To check if your code matches the expected style, the following commands are helpful:
  - `git clang-format-14 --diff`: Show what needs to be changed to match the expected code style
  - `git clang-format-14`: Apply all needed changes directly
- - `git clang-format-14 --commit master`: Fix code style for all changes since master
+ - `git clang-format-14 --commit main`: Fix code style for all changes since main
 
 If existing code gets reformatted, this must be done in a separate commit. Its commit id has to be added to the file
 `.git-blame-ignore-revs` and committed in yet another commit.
