YogBox Install Notes
[[[[[ THIS VERSION OF THE YOGBOX WORKS ONLY WITH MINECRAFT VERSION 1.7.3! ]]]]]
Make sure you have a fresh MINECRAFT.JAR before installing (use the force update option in your Minecraft launcher)! Also if you have an existing MODS and/or MILLENAIRE folder, remove them/back them up before installing to avoid possible issues! Alternatively you can use the Uninstaller first and select the 'Uninstall Yogbox (ignore backups)' option, then use the force update option in your Minecraft launcher.
Extract the contents of this zip into its own folder, then run the YOGBOX Installer.jar and follow the on screen prompts. Selecting no optional mods will install the core experience.
