-(Explainations of more crafting types are coming soon)
+###Shapeless
+
+Shapeless recipes are a type of recipe that can be used when a flexible crafting
+recipe is wanted.
+For example, when you craft a bronze ingot, the steel and the copper do not
+need to be in any specific place for it to work.
+
+{% highlight lua %}
+minetest.register_craft({
+	type = "shapeless",
+	output = "mymod:diamond",
+	recipe = {
+		{"mymod:diamond_fragments" "mymod:diamond_fragments", "mymod:diamond_fragments"}
+	}
+})
+{% endhighlight %}
+
+When you are making the diamond, the three diamond fragments can be anywhere
+in the grid.
+Note: Other options, like the number after the result, found in the shaped
+crafting recipe, can be used here, and for some of the other craft types.
+
+###Cooking
+
+Recipes with the type "cooking" are not made in the crafting grid, like
+other recipes, but as the name suggests, they are cooked, in furnaces,
+or other cooking tools that might be found in mods.
+This is the way that anything that must be cooked, like bricks, or
+can be cooked to turn into something else, like cobble, are defined.
+
+{% highlight lua %}
+minetest.register_craft({
+	type = "cooking",
+	output = "mymod:diamond_fragments",
+	recipe = "default:coalblock",
+	cooktime = "10",
+})
+{% endhighlight %}
+
+From this example, you can see that the only difference in the code,
+between this type of crafting and any other (apart from the type), is
+that the recipe is just a single node, and it is not in a table (between
+braces). They also have an optional "cooktime" parameter, which defines
+how long the item takes to cook. If this is not set, it defaults to 3.
+So, for this to work, the coal block is in the input slot, with the fuel
+below it, and the diamond fragments will come out on the far side
+of the furnace, after 10 seconds!
+
+####Fuel
+
+This type is an accompaniment to the cooking type, as it defines
+what can be burned in furnaces and other cooking tools from mods.
+
+{% highlight lua %}
+minetest.register_craft({
+	type = "fuel",
+	recipe = "mymod:diamond",
+	burntime = 300,
+})
+{% endhighlight %}
+
+They don't have an output, like other recipes, but they have a burn time,
+which defines how long they will last as fuel, in seconds. 
+So, the diamond is good as fuel for 300 seconds!
+
+###Tool Repair
+This is a fairly simple type of craft. It simply allows two tools, of the
+same type,  to be crafted together, and produce a tool with the
+combined wear of the two separate tools, minus the additional wear
+as defined in the additional_wear field. 
+
+{% highlight lua %}
+minetest.register_craft({
+	type = "toolrepair",
+	additional_wear = -0.2,
+})
+{% endhighlight %}
+
+This looks very different from other crafts! The only field (other than
+type) that it has is a field that looks rather strange. It defines the amount
+of wear subtracted from tools that are repaired. Because it is subtracted,
+negative values make the new tool more  durable. -1 means that any 2
+tools will form to make a new one without any wear, while 1 disables
+it, because even 2 new tools will make a tool with 100% wear!
+So, in the example provided, two tools crafted together will regain 20%
+of the total wear, along with the amounts of use that both tools had
+left.
