For modpack makers (versions 1.20.1, 1.21.1), Patchouli content is stored in the following directory:
instance/patchouli_books/<your_book_name>/
Inside this folder, the structure must follow this pattern:
* book.json: Defines the book's name, landing page text, and visual style.
* en_us/categories/: Contains JSON files for each category.
* en_us/entries/: Contains JSON files for each entry.
* en_us/templates/: Contains custom page layouts.
Note for 1.20+: Patchouli now enforces the use of the Resource Pack system. While the book.json remains in the data folder, all content (entries and categories) should be placed in the assets folder of your mod or resource pack to ensure proper loading and compatibility.
