====== update your doc files for help ======
If you install a plugin, it often comes with a file to place in the vimfiles/doc folder.  This file may show up in the local-additions section of the help contents, but you can't search or use it yet.  You need to make a tags file:
<code>
:helptags ~/vimfiles/doc
</code>

(change vimfiles to your [[vim_files_location]]
