1. Install modloader.
2. Install forge api, you can install latest version but I've only tested 3.0.1.75 version.
3. Install CampCraft by draging all files inside the "Goes into minecraft.jar" into your minecraft.jar.
4. Changing block/item ids or dissabling mods, go into ".minecraft/config" folder and open "mod_CampPack.cfg"
*you can open it with any text editer programs for example wordpad/notepad/TextEdit.
