 Geyser is a bridge between Minecraft: Bedrock Edition and Minecraft: Java Edition, closing the gap from those wanting to play true cross-platform.
 
+Geyser is an open collaboration project by [CubeCraft Games](https://cubecraft.net).
+
 ## What is Geyser?
 Geyser is a proxy, bridging the gap between Minecraft: Bedrock Edition and Minecraft: Java Edition servers.
 The ultimate goal of this project is to allow Minecraft: Bedrock Edition users to join Minecraft: Java Edition servers as seamlessly as possible. **Please note, this project is still a work in progress and should not be used on production. Expect bugs!**
 
+Special thanks to the DragonProxy project for being a trailblazer in protocol translation and for all the team members who have now joined us here!
+
 ### Currently supporting Minecraft Bedrock v1.14.6(0) and Minecraft Java v1.15.2.
