Do you have any additional resources for GitHub?
The GitHub website is full of tutorials and support decks. And for a visual tutorial on branching, we recommend this animated interface.
The key to becoming comfortable with Git is practice. The more you code, the sooner you'll build those Git skills! You might also take a look at these resources:
Git for Humans (It's a paid resource but it's very well written and easy to read.)
How Git Works! is a paid resource.It looks like an approachable way to learn more about Git
Git Docs (It's a bit dense. But a good place to find everything about Git. Then you can check out other resources that may be easier to read.)
