Some plugins just aren’t suitable for the WordPress.org plugin repository or, if your like me, maybe you use Git and find SVN a pain in the butt. Either way WordPress doesn’t have a way to update plugins outside of the WordPress plugin repository.

Lucky for us @jkudish wrote the WordPress Github Plugin Updater. Today we’ll look at adding it to our plugin so that we can update them for clients.

I’ve been using a similar method for my own theme and plugin updates lately so it’s nice to see other people with the same idea.
