If you're not familiar w/ TeX, and if _The Art of Computer Programming_ seems tough sledding (but interesting), may I suggest:

https://www.amazon.com/Literate-Programming-Lecture-Notes-Do...

You could check out:

http://literateprogramming.com/

to see if it's a good fit. Hopefully it will get reprinted soon, but there are still copies available at fairly reasonable prices.
