The .gitconfig in this repository has aliases that should make some git commands more convenient to call. For example, aa is the alias for add all.
So you can run the command below to add all updated files to your commit
git aa
Another example is c which is the alias for commit -m. You can run the command below to commit with a message
git c "Your commit message."
See the .gitconfig file for a list of all aliases and add the ones your like to your .gitconfig file.
