I would also recommend against installing "kitchen sink" plugins (plugins that do a lot of little things). Use the editor as is and figure out exactly what's missing that you need and go from there. In the case of this old plugin, a lot of that functionality exists by default now.
While there isn't a lot of formal documentation - there are ways to figure out the editor. It just requires a bit more effort than a wiki would provide. Start with the keybinds file (Preferences, Key Bindings - Default). I skimmed through this file when I first started using Sublime and it helped a LOT. It will also help to illustrate the power of the editor as well as the customizability (I think I just made that word up). Also, don't be afraid to ask. I've found the ST2 community to be very nice. Not the usual "lrn 2 srch noob" mindset that a lot of forums have.
