title: Git add on repository sub directory returning 'fatal: [FOLDER] is outside repository'
body: <p>I have a website that I need to commit system generated files and folders to an existing git repository via linux command line.</p>
  
  <p>I've pulled the repo to my server, and am writing files within a sub folder of the repo, but when I run <code>git add [FOLDER]/*</code> , its giving me an error that the folder is outside the repository. I'm at a loss as to how to get past this. I'm brand new to git, please help!</p>
