title: How do i switch to an 'unstable' branch using git?
body: <p>I'm testing out a package (git clone git://guacamole.git.sourceforge.net/gitroot/guacamole/guacamole)</p>
  
  <p>This project has two branches: 'master' and 'unstable'</p>
  
  <p>How can I get the 'unstable' branch ?</p>
  
  <p>Sorry for the dummy question, but 'git branch' only shows 'master'.</p>
