I don't know TeX either and it could be a way to force myself to learn, thanks for the suggestion.
I did assume previous knowledge for this chapter, but everything you need has been shown in the ~10 previous chapters. So far, the book is still meant to be read in a linear manner, but this could change once enough material is covered. I could add a few more links in a wiki-like manner.
Thanks for the positive comments, too. Much appreciated.
