 In this tutorial, we'll build a simple rougelike inventory, where we expect items to have a "weight", and we can carry as many items as we want, as long as we don't exceed our "max weight".
 
-Inventories and items in Artery are just tables, as per usual in lua. They have a few required fields each. On the left, under "Classes" (all the way at the bottom!), open invtbl and itemtbl in new tabs.
+Inventories and items in Artery are just tables, as per usual in Lua. They have a few required fields each. On the left, under "Classes" (all the way at the bottom!), open invtbl and itemtbl in new tabs. invtbl contains a list of methods every inventory has, and itemtbl contains a list of methods every item has.
 
 ## A simple inventory
 
 You can see all the fields needed for an inventory, so let's get started. Recall that
 
 	function tbl:func_name(one)
+		print(self.Name)
 		...
 	end
 
 is the same as
 
 	function tbl.func_name(self,one)
+		print(self.Name)
 		...
 	end
 
-lua will automatically create the variable "self" in the first example
+Note the period `tbl.func_name` versus the colon `tbl:func_name`.
+Lua will automatically create the variable "self" in the first example
+
+and that the function calls:
+
+	sometable:dothing("blah")
+
+is the same as
+
+	sometable.dothing(sometable,"blah")
