User Guide

Is there any user guide out there beyond the tutorial? Not talking about strategy guides but a users guides on the actual UI like what do all the icons mean, what happens when you click on them, how to do missions and read the missions screen, how the store works so you don't accident buy something you don't want, when you click on an enemy ship what do all those options mean, etc. I've been figuring out thing via trial and error so far but I know there are things I'm missing or not understanding. Thanks!
