Help Setting up a new D&D 5e Realm

[The_Traveller]

So with the possibility of there being a chance that sometime in the near future on a yet to be determined date we may be allowed to be in the same room with other people I was planning to setup a new D&D master realm.

In this case it would contain all the core mechanics sections (classes, races, items, spells, etc). I will then export this realm as the basis for the adventure realms (One for each book, One for each AL season, etc).

Now, while I own at least 2 copies of all the core rule books (PHB, DMG, MM, XGtE, MToF) I was not going to type all that it. I'm using the import tool and that website that has already converted the books into json files.

Among my issues is the best way to layout the various sections when planning my imports. Has anyone ever done this before, i'd love some suggestions.
