It's pretty overwhelming to open it and be met with 87 categories and 3,000 pages when you've never used the mod before - especially since it's not made clear where you should start due to the "Getting Started" category having a ton of pages that don't feel very relevant to the new player experience.

Applies to every version (as far as I know, at least - only used it on 1.21.1), but I'm not sure if old MC versions still get mod updates.

We are in the process of rewriting documentation from the ground up natively instead of using patchouli #1517

that will also include advancement based progression with an option to unlock everything immediately.

Noice. I like custom guidebooks a lot more than patchouli, but do understand why most mods forego it.
