title: Version control and git checkout/clone
body: <p>I am using Bootstrap SASS. I learning git slowly. I want to be able to update files located in folders from this repo on git when they are updated, however I don't want to clone the entire repo, as I use a different file structure. As an example:</p>
  
  <p>Bootstrap SASS holds the js files here:</p>
  
  <pre><code>https://github.com/twbs/bootstrap-sass/tree/master/vendor/assets/javascripts/bootstrap
  </code></pre>
  
  <p>My local js files are here:</p>
  
  <pre><code>app/assets/javascripts/scripts
  </code></pre>
  
  <p>In my local directory I have additional scripts which I concat in with bootstrap .js files. My question is, How would I clone/update the files in a folder from the bootstrap SASS repo to the local repo without having conflict with the addition scripts inside my local repo and not having to clone the entire repo, just the files or better yet particular files. </p>
