title: git gui: how to clone and push?
body: <p>I think I am stupid. I don't understand how Git works with the command lines so I am using Git Gui.</p>
  
  <p>I got it install and the Gui can be launched successfully, but when I come to clone the file from the files which is shared by another programmer with me, I keep getting this error message,</p>
  
  <p>Location C:/.... already exists.</p>
  
  <p>on the Gui interface, it has two input fields to fill in only -</p>
  
  <pre><code>'Source Location' : https://me@github.com/remote-programmer/project-1.git (for instance)
  'Target Directory' : C:/wamp/www/project-1-folder (for instance)
  </code></pre>
  
  <p>any visual guides available that I can avoid the command lines?</p>
  
  <p>thanks!</p>
