Git mystifies me, too. I also did a lot of reading but it was written my Martians.

Also, pointers in 'C' confound me; that's what stops me reading source. 'C' programmers tell me they 
are like assembly language, and I know 4 or 5 assembly languages (in addition to about 7 HLLs), but 
"like assembly language" doesn't work with me. It doesn't make sense to me that authors should need 
to remember which variables are pointers to variables and which are actual variables. I don't know 
why anyone would think that two references with two different names is useful. I know that 'C' has 
'.h' files but I don't see why those '.h' files don't fix-up the pointer references automatically.

Mark.
