These instructions are to install the Underground Biomes mod for Minecraft 1.4.7. This requires Forge version 6.6 or higher.

If you already have the Minecraft Forge installed go to 3.

1.	Install the latest version of Minecraft Forge from http://www.minecraftforge.net/forum/

2.	Once Forge is installed run Minecraft once to make sure it has worked and to set up the necessary folders.

3.	Put the contents of the 'Add contents to mods folder' folder into your mods folder in the minecraft directory. If there is no mods folder then 
	Forge might not have installed correctly.

4.	Run Minecraft. If Minecraft loads and the mod shows up when you click the mods button in the main menu then it has worked.

Config:

You can edit the mod config file if you want by going to the config folder in your minecraft directory and opening 'UndergroundBiomes.cfg'
with Notepad or any other text editor. You can set all the block and item IDs for the mod here to fix any conflicts that may occur with other mods.
