I should explain.......
A "how to" is going to be tricky, because there's going to be a lot of opinion injected (how many strands works best, what material is best, etc. etc. etc.), different bowyers have different requirements (padded loops not required, 16 strands in the loops minimum, 20 strands minimum, etc.--what is required for one may make the string too big for the grooves on another), etc. etc. etc. Then you will find that some bows "like" one material better than another (that's the only way I know how to put it).
I don't claim to know it all (not even close), but I'll try to help with questions.
