1. Download ether ModLoader or Minecraft Forge, and this mod.
2. Install Modloader or MinecraftForge for the version you are wanting.
3. Run Minecraft to generate. If you get a black screen, you may have forgotten to delete the META-INF file in the minecraft.jar. If it takes you to the Minecraft Main Menu, then close out Minecraft and Continue the install.
4. Go to you .minecraft folder and Drop the mod into the mods Folder. If there is no Mods Folder, ether you did not run Minecraft after installing ModLoader/MinecraftForge, or it simply didn’t generate for some odd reason. If this happens, just create a folder named mods and place the mod into it.
