title: Setting Up Environments with SaltStack
body: <p><strong>How do I make minions use a particular SaltStack environment?</strong></p>
  
  <p>The <a href="http://docs.saltstack.com/topics/tutorials/gitfs.html?highlight=gitfs#branches-environments-and-top-sls-files">GitFS backend tutorial</a> states that <em>branches will be mapped to environments using the branch name as identifier</em>. How do I expose these environments to my minions?</p>
  
  <p>As an example, let's say <a href="https://github.com/rgbkrk/salt-nbviewer">I have a branch</a> named "pippy". I'd like to deploy that branch to particular minions.</p>
  
  <p>It seems like I can set the environment via the minion's configuration file. Are there other ways that can be done from the salt master?</p>
