Cakephp .htaccess/Mod_Rewrite with hosted site

Currently you can access my website with something like this www.xxxx.com/xxxx/source/....now my question is how would I alter my .htaccess file so I can access my site like this www.xxxx.com/xxxx? I have looked around on the web but I don't have a clear understanding of mod_rewrite.Any input would be greatly appreciated! Thanks!

My .htaccess file is as follows

   <IfModule mod_rewrite.c>

RewriteEngine on  RewriteRule    ^$    webroot/    [L]  RewriteRule    (.*) webroot/$1    [L]
