title: Cannot find colour scheme
body: <p>I am trying to install a colour scheme called "github", which I got from the vim site and I have followed exactly how to install it by adding <code>github.vim</code> to my <code>~/.vim/colors</code> folder. However, I get the error message "Cannot find colour scheme <code>github.vim</code>" after executing:</p>
  
  <pre><code>:colorscheme github.vim
  </code></pre>
  
  <p>I can't seem to find the issue after searching countless posts for a solution, so if anybody could help that'd be great. :)</p>
