Getting Started with GitHub
The first thing you will need is a GitHub account. If you don’t already have one, go to github.com.
Next, you need to make sure that the email address you have associate with your Git installation (i.e., git config) is the same as the email address associated with your GitHub account. This is how GitHub knows it is you!
git config --global --get user.email
If the previous cell doesn’t return an email address that matches the email address you used for your GitHub account, then you should change it with the following line:
git config --global user.email you@domain.example.com
And that’s about all you need to do to get started with GitHub. We’ll be going back and forth between the GitHub website and wherever you have Git installed for the remainder of this section, so you might want to bring up GitHub in another tab of your browser.
