How to Open and Navigate a Guide Book Added by a Mod

Finding the book

Mods that use Guide-API register their guide book as an item and place it in the Guide-API creative tab. If you are in Creative mode, open the creative inventory and look for that tab, then drag the book into your hotbar. In Survival, the book is usually given to you by the mod itself (for example as a starting item) or crafted with a recipe the mod defines. Check the mod's own recipe list if you do not already have one.

Reading it

Hold the book and use it (right-click by default) to open the guide screen. The home screen shows a list of categories on the left or as icons. Click a category to open it, then click entries to read pages. Use the arrow buttons at the bottom or the side of the page to move forward and back. Some pages contain crafting or smelting recipes rendered as grids; hover over an ingredient to see what it is. If a page references a keybinding, the guide shows the key you currently have bound, so it always matches your controls.

Getting back

Press the back arrow to return to the previous page, and the home button to jump to the top level. Press Escape or the inventory key to close the book. Reopening it returns you to where you left off in most cases.
