title: How to add my current project to an already existing GitHub repository
body: <p>I'm very new to Git. I've been searching for an answer, but I couldn't find one.</p>
  
  <p>In my computer I have a project folder like this:</p>
  
  <pre><code>project_a
  --some_folder
  --another_folder
  --.git
  </code></pre>
  
  <p>And I have a repository on GitHub, let’s say <code>https://github.com/company/our_repo.git</code>. Under this repository I have some folders. So my goal is to put my <code>project_a</code> under <code>trunk/bin</code>. How do I achieve this? (Again, I'm very very very new.)</p>
