title: Getting grunt.js to work on a pre-existing yeoman project
body: <p>I have a working yeoman project, which I run the server with <code>grunt server</code>, it works fine.</p>
  <p>I put the entire thing into a git repo, and checked it out to a new folder...</p>
  <p>when I try doing 'grunt server' it says:</p>
  <blockquote>
  <p>Fatal error: Unable to find local grunt.</p>
  <p>If you're seeing this message, either a Gruntfile wasn't found or grunt
  hasn't been installed locally to your project.</p>
  </blockquote>
  <p>I am having trouble getting grunt installed locally to that directory, and being able to locate and use the GruntFile.</p>
