git is already installed, but let's just make sure by running this command in the terminal area at the bottom (blue area).
$ git --version
You should see a version number returned like:
git version 2.8.3
Now we'll set up Git. Make sure to use the same email you used for your Github and Heroku accounts. run these commands below, replacing the placeholders with your information.
$ git config --global user.name "ENTER YOUR ACTUAL NAME"
$ git config --global user.email "ENTER YOUR ACTUAL EMAIL ADDRESS"
Now let's make sure that worked. In your Terminal type:
git config --get user.name
Note:You should see your name.
git config --get user.email
Note:You should see your email.
