User's Guide for 1.1.28?

Feb 3, 2011
Is there a user's guide for the MIUI 1.1.28 release? I'm finding a lot of scattered tips and tricks from different forums in different threads. Is there a "one stop shop" for all such tips and tricks? This ROM seems to have so many features that other Android ROMs do not, so I would think that there would be some kind of documentation out there somewhere...
