Creating Plugins

I spoke with Frank a bit at the SMD Symposium and mentioned a little addon script that I use for doing a lot of things in Cesium. He mentioned me potentially wanting to go ahead and just make it a plugin. I took a break for a minute today and looked around and I see some documentation about the plugins but I haven't spotted a... "Here's the advantage of using plugins", "Here are the steps to create a plugin", "Here is the structure of a plugin". Does this exist somewhere that I just haven't run across yet?
