If you have not done so already, you may wish to set a name and email that
will be associated with your commits (see Telling Git your name in Git User Manual). If you wish to use a
different name or email just for commits in this repository, you can use
git config --local, or edit .git/config in the repository
instead of ~/.gitconfig.
Other important Git configuration will automatically be configured when building the project (see 从 Git 构建). A .git/hooks/commit-msg hook will be installed that embeds ‘Change-Id’ Git trailers in your commit messages for traceability purposes. It is important to preserve these when editing your commit messages, particularly if a first version of your proposed changes was already submitted for review. If you have a commit-msg hook of your own you would like to use with Guix, you can place it under the .git/hooks/commit-msg.d/ directory.
