Replace the example values in the following commands with your own information.
git config --global user.name "Jane Doe"
git config --global user.email jdoe@dewv.net
git config --global credential.helper 'cache --timeout 5400'
git config --global credential.https://github.com.username jdoe@dewv.net
These commands store your name, email, and github username so that you don't have to keep typing them. Also, git is configured to cache your github password for 90 minutes, so that you don't have to repeatedly type it.
