I pushed six commits to my repo on GitHub and I had no idea the importance of adding a gitignore file. The request I have is:
Some things in your repo need to go. Add a standard .Gitignore file and make an interactive rebase so you can't see it was added from the start.
I honestly don't understand this sentence, am I not supposed to do the opposite? Make sure you can't see it wasn't added from the start?
