Question 1

What is Git, what problem does it solve?

Git is version control for our projects. A way for us to snapshot a moment of time in our work so that we could go back to that exact moment if we wanted to. For example if we took a snapshot of a moment where our project is working perfectly but then proceed to add more code that ultimately broke our code, we could go back to that snapshot and continue with where we left off.

Question 2

Describe the homework submission process.

We are suppose to fork the homework repo so that we have a copy of the repo under our username on github, then we clone the remote repo under our username down to our local machine to start editing content. Once the homework is complete we would add, commit, and push our code back to our repo on github. Finally we submit a pull request to upstream (the original remote repo) so that GA will see our changes.

Question 3

What is the difference between a fork and a clone?

When you fork a remote repo you copied the repo onto your account on github. When you clone a repo you will have a copy of the original repo on your local machine.

Question 4
