 ## 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!**
+The ultimate goal of this project is to allow Minecraft: Bedrock Edition users to join Minecraft: Java Edition servers as seamlessly as possible. However, due to the nature of Geyser translating packets over the network of two different games, *do not expect everything to work perfectly!*
 
 Special thanks to the DragonProxy project for being a trailblazer in protocol translation and for all the team members who have joined us here!
