+GeyserMulti is an easy way for Bedrock Edition clients to connect to any Java Edition servers without having to run anything.
 
 ## What is GeyserMulti?
-GeyserMulti is a server that Minecraft: Bedrock Edition clients can connect to that allows for a list of Minecraft: Java Edition servers to be displayed and accessed through 1 public geyser instance. It is effectively a combination of [BedrockConnect](https://github.com/Pugmatt/BedrockConnect) and [Geyser](https://github.com/GeyserMC/Geyser).
