README.md

The ViaVersion suite allows server owners as well as players to allow client connections to servers of different Minecraft versions through a bit of magic™. We support Paper, Velocity, Fabric, Forge, Sponge and have our own standalone proxy to join from basically any client version on any server version from the past decade.

See HERE for an overview of the different Via* projects.
