I'm relatively new with using TeX and primarily use it for writing Mathematics. However a colleague of mine is looking to use TEX for its typesetting properties to actively work with typeset pages.Using the page format commonly seen in the Mishna Brura

If anyone knows how to get started with this it will be greatly appreciated!
