IGW (in-game wiki) is not ported to 1.12 and I'm not very inclined to port it.

McJty's upcoming Lector mod may be a good solution here.

Now that IGW is ported to 1.12.2 is it not as simple as copying the pages from the 1.7.10 Pneumaticcraft version? For the old stuff at least.

Actually, IGW support is already in. Wasn't quite as simple as copying the data files due to Mojang lowercasing requirements, but it's pretty much working.

Oh good, guess I need to update my PNC:R then.

Yep, it's changing very fast right now :)
