No is the simple answer, well not on one place. ie if I want to know what a plugin does, I google the plugin name. You may find basic setup guides but when it comes to guides on everything you can do on the box it's a trial and error and does depend on the build your using, ie on my own build and wooshbuild the green button brings up the plugin browser, I don't think this is the case on Dsayers H2H image, I think on his the green button and portal button are the opposite.
