Tutorials/Installing a snapshot

Follow these three steps to install a snapshot:

Step 1: Navigate to the snapshot history page and download the client version on the right of the snapshot description.

Step 2: Go to your .minecraft folder: Step 3: Replace "minecraft.jar" in the "bin" folder there with the one you downloaded, and start Minecraft.
 * Windows XP/Vista/7/8:  (Simply put this in your address bar & hit enter)
 * Linux:  (this folder may be hidden in the "Home" folder)
 * Mac OS X:  (this folder may be hidden)

Congratulations, you have installed a snapshot!

Warning 1: Opening existing single player worlds is not without risk: they might become broken or unloadable. If you load the map in the new snapshot & later you downgrade your version of minecraft, the map might contain items that don't exist in that version yet, thus corrupting it. A map can also become corrupt by any bugs in the new snapshot. Don't take any risks: backup your saves! (they are in \.minecraft\saves\)

Warning 2: To make a backup of your minecraft mods, make a backup of the minecraft.jar. Simply copy the file to a safe location (The file is in \.minecraft\bin)

To revert to the stable version, click "Force Update" in the launcher. You can download the snapshots at mojang.com
