title: What is the master branch and release branch for?
body: <p>The &quot;<em>Master branch</em>&quot; is for a product which is ready and can be downloaded by end-users.</p>
  <p>But there are &quot;<em>release branches</em>&quot; - I have no ideas who these branches are for. Release for customers? For QA?</p>
