Show steps for initializing a new Git repo

[codykaup]

It can be a little confusing when you try to run Chromatic in a directory that isn't a Git repo. You end up going through a couple of error steps before you finally get to a workable state. This adds a suggestion how to initialize an empty Git repo and add a single commit. Therefore, you only go through 1 error before you can run a build.

Looks good. Would it make sense to perhaps link to the git book? If you're unaware of how to create a git repo, more docs would probably be a good thing. https://git-scm.com/book/en/v2

Excellent idea! I'll toss that in there too!
