-#### A Crafting Guide for Minetest that doesn't suck. ####
+#### `craftguide` is the most comprehensive crafting guide on Minetest. ####
+#### Consult the [Minetest Wiki](http://wiki.minetest.net/Crafting_guide) for more details. ####
 
-#### `craftguide` is the most comprehensive mod of its category. ####

-#### This crafting guide is usable with a blue book named *"Crafting Guide"*. ####
 
 #### This crafting guide features two modes : Standard and Progressive. ####
 The Progressive mode is a Terraria-like system that only shows recipes you can craft from items in inventory.
 The progressive mode can be enabled with `craftguide_progressive_mode = true` in `minetest.conf`.
 
+`craftguide` is also integrated in `sfinv` (Minetest Game inventory) when you enable it with
+`craftguide_sfinv_only = true` in `minetest.conf`.
