Installation for the new launcher

 * Open the new launcher and make sure the version of Minecraft the mod requires is already installed.
 * Click "Edit Profile" in the launcher, then open the game directory.
 * Go into the subfolder "versions".
 * Rename the folder for the version you require to something else. In this example, rename "1.6.2" to "1.6.2_Modded".
 * Rename "1.6.2.jar" to "1.6.2_Modded.jar".
 * Rename "1.6.2.json" to "1.6.2_Modded.json".
 * Open "1.6.2_Modded.json" with a text editor an replace "id":"1.6.2" with "id":"1.6.2_Modded", save the file and close it.
 * Open the class files from the mod with an archiver such as WinRAR or 7-Zip and copy-paste the files into 1.6.2_Modded.jar.
 * Delete META-INF.
 * Start the new launcher.
 * Click "Edit Profile"
 * In "Use Version", select "1.6.2_Modded".
 * Click Save Profile.
 * Login and play as normal.
