Thanks for the kind words :). Beauty can be subjective, but here is something we’re striving for https://moot-books.github.io/moot-KTU/CSE/S6/CN_CS306.pdf. Initially we would typeset the books using vanilla LaTeX which produces the standard quality books you expect from traditionally publishers. In the long run the goal is to produce books that look similar to this https://ctan.math.washington.edu/tex-archive/macros/latex/co... , but optimized for readability for different book types.

English is not my first language, but its still no excuse, I had run it through Grammarly, will check again for mistakes.
