title: Add files to local repository in GitKraken
body: <p>Am new to GiKraken.</p>
  
  <p>I have created a local repo and remote (origin) repo.
  I have added some files to the local repo (folder on my computer).</p>
  
  <p>But, Gitkraken cannot find them automatically and then cannot commit.</p>
  
  <p>How to add them in GiKraken manually ?
  (could not find the way to do it, even "Stage" is not shown inthe community version).</p>
