 This is the server for the multiplayer mod **[BeamMP](https://beammp.com/)** for the game [BeamNG.drive](https://www.beamng.com/).
 The server is the point throug which all clients communicate. You can write lua mods for the server, detailed instructions on the [BeamMP Wiki](https://wiki.beammp.com).
