In-Game Wiki Mod
The mod started as a Modjam 3 mod, and has been finished. The mod is fully implemented in an other mod of mine, PneumaticCraft. To see what's possible with this mod I recommend installing PneumaticCraft as well.
The mod is meant to be a client-only mod. However, it can be installed on a server. Server owners can add server information on their server which the users will see when they log on the server.
