Here's some unsolicited advice:
Before you change a string, video tape the bow and take pictures. Take pictures of how everything is routed, even how the cables cross and go through the cable guard. I also will label my cables and such as "top" and "bottom" for the different sides (using masking tape) prior to removing them. It is common for people to go off memory and misroute a cable. I review the pictures/videos as I'm working even if I don't think I need to.
Get a notepad and write down everything you do to the bow so that you can undo it or do it the same way to the next bow. For instance, I know how many twists I added to each cable and string during my last string change and even what I did to get my peep sight aligned.
Before you change a string, measure everything: axle to axle, brace height, draw length, draw weight, and where your d loop, peep, etc are at on the string. Before my last string change, I put masking tape on a bow square and marked exactly where my old d loop and nock sets were in relation to the rest (marked a line on the tape).
