In what way is it not newbie friendly? It tells you the address of every table, how big it is, and how to repoint them. It translates all ASM changes to byte changes at specific addresses. It literally gives to someone with zero knowledge of the pokedex and all pokemon species related functions the ability to expand the dex. The most you could say is that there are more steps involved than the typical tutorial, but that's because the sheer number of things involved in the number of pokemon. You could call it tedious, but none of the steps involved require the person reading the tutorial to have advanced knowledge.
