We made a big dent in the cPanel section yesterday. We have a lot more articles to come, as well as updates to the existing ones we already have.
Right now our biggest goal is to flesh out the main sections, like cPanel, and then go back and make all the articles more in-depth, plus add links to related resources.
The site might look like a mess right now, with random content thrown all over the place, but there actually is a plan. Something like this is built in pieces, and if you have found us this early in development, you actually will witness what it takes to build a support guide.
