+Example Code
+============
+
+Along with this mod, you should also download my template mod, which is quite 
+easy to transform into whatever mod you want to create that needs this mod.
+
+It's just a skeleton, but all you should need to do to get started is to rename 
+the folder to whatever your mod will be named, tweak a few variables near the 
+start of the template's init.lua, and follow the above instructions regarding 
+the creation of your textures.
+
+If you do it right, you should end up with a very basic mod giving you craft 
+and /give access to your various items.  After that part is confirmed working, 
+just add whatever code you need to the end of the init.lua to define additional 
+functions, items, crafts, and smelting recipes, etc., as needed by your mod, 
+and start coding and testing like usual.
+
+This template is not supplied as part of the unifieddyes mod, rather you need
+fetch it separately from here:
+
+Download Template:  https://github.com/VanessaE/modtemplate/zipball/master
