Am not sure if am doing something wrong or if it's the mod's problem but my book will not appear in-game. Am using Patchouli v 1.1-24 MC v 1.14.4 and after following the wiki and launching my game, I use the /give command but my the only thing that shows up under patchouli: is patchouli:guide_book , which is just an item(no special functions). Here's my path if it helps:

• patchouli_books
  • quest_book(folder, my book's name)
    • en_us(folder)
      • categories
      • entries
      • templates
    • book.json(JSON File)

Here are the contents of the json file:

{
"name": "Quest Book #1",
"landing_text": "This is the",
"version": 1
}

you need to specify your book in the nbt tags. Here is something that should work:
/give @p patchouli:guide_book{'patchouli:book': 'yourdomain:quest_book'}

where yourdomain is either your modID (if you're a modder), or the subdirectory of /data/ your patchouli_books folder is located in.
