title: Adding a Supporting File to xcode project
body: <p>I am new to xcode, and development in general.  Following a tutorial that tells me to add "file.plist as a supporting file to the project."</p>
  
  <p>Does this just mean add a file to the project?  I placed it into a folder (BT_Config) that has the another .plist file in it already).  Not knowing anything about my project, does that sound right?  </p>
  
  <p>I can't find a clear google reference to "xcode supporting files" - so i'm not sure.<br>
  Any suggestions?</p>
