# 1. First make sure you copied the Gerrit commit-msg hook (from Gerrit to your local repos .git/hooks folder)

# 2. Make the code changes needed and then stage them using the usual command
git add . -A

# 3. Now commit them using amend and notice that the previous commit message is used but is suffixed with the Change-Id of your previous commit. Make sure you leave that (even if you modify the commit message). Note: modifying the commit message will overwrite the previous one.
git commit --amend

git push origin HEAD:refs/for/master
