Upgraded to latest (5.8). Woot guide wasn't in the akashik tome, so I tried to craft one. NEI says you need the guild-api mod installed to access the manual.

Seconding.

While this is true, if you type in jei guide, you will see that there is another book called woot guide made with a book and zombie flesh. guide-api is in the pack already, its just woot adds that uncraftable item to tell you where to look.

Guide-api is already in the pack.

As @FallenEagle1 correctly states "woot guide made with a book and zombie flesh."
