 The automatic crafting is only operable when the crafter is in an active
 block. Mesecons and digilines operations operate in unloaded blocks.
 
+When crafting by item, if more than one recipe is satisfied by the input
+items, the crafting grid is replaced with the available crafts for that
+item. Clicking the < and > buttons walks through the recipes. Clicking
+Craft performs one craft with the displayed recipe. Clicking Close displays
+the crafting grid. If only one recipe is satisfied by the input items one
+craft is immediately performed without displaying the recipe.

 Hoppers placed to the top or sides of a crafter will feed items into the
 input. Hoppers placed below a crafter will take items from the output.
