Starexplorer

Required for having a custom Patchouli Book item for Starexplorer.
Simply download this file and rename it from patchouli_books_convert_to_zip.jar to patchouli_books.zip Then, uncompress-it and extract the folder that should be placed directly at your .minecraft root. If Patchouli is installed, it should add a custom book in the inventory.

If moderators see this or someone wants to directly help me embed the stored folder inside the mod directly, I'm interested since I don't actually know how to do that yet.

If this gets interpretted as misleading since it's a .jar file (actually a folder containing .json entries), just use the instructions and help from in-game.
