Origin is a large library (written in Scala) which can be used as an API or as a foundation for a new mod. In my opinion, this mod is a useful mod and will satisfy Minecraft players.

It includes:
- An API.
- A foundation to make other mods on.
- An internal mod, for tweaking the minecraft experience.
- Addons.

- Type %appdata% into the Run program, and press Enter.

- Drag and drop the downloaded jar (zip) file into that.
- Enjoy the mod.
