+If you click on a mod it will show some info about it. The install instructions there are usually for manual installs.
 To get started, click on a mod and select Install mod. Most mods need GamecraftModdingAPI as well.
 Then, simply click Play. This will first download and run the patcher (GCIPA) if needed.
 If all goes well, after some time a modded Gamecraft should launch.
 
 After a Gamecraft update there's a good chance that mods will break. If this happens you may get errors when trying to start Gamecraft.
-Until updated versions are released, use the ""Run unpatched"" checkbox at the bottom to launch the game without mods.
+Until updated versions are released, use the ""Disable mods"" checkbox at the bottom to launch the game without mods.
 
 You don't have to use the mod manager to run the game each time, though it will tell you about mod updates when they come.
-However, make sure to click Play each time you want to switch between modded and unmodded.
