/ retroactively gitignore
Created

Remove any files from the repo that are in the gitignore, even after the fact. Just copy paste the whole thing into terminal/commandline (in the correct directory) and it will un-track the files (but leave them intact locally).Then use git status to verify nothing important was removed.
