updated tutorial

I have the latest version of blender but the manual I downloaded covers an older version.Some of the buttons shown in the manual aren’ t in the version I have.I can’t get some of the functions to work right.I can’t afford a book right now.I am having trouble getting the rigging to work right.I have seen lots of examples of blender projects and can see it is a great program…IF you know how to make it work.I have used other software and blender is set up so different.Too many frustrations make learning something new not worth the trouble.Any help with updated material would be appreciated.
