This is an educational Decentraland communications client, meant for developers to understand the inner workings of the system. It can discover realms, connect to their RPC interface, use Archipelago to get an island assignment and join the island to chat with nearby players and inspect their profiles.
If you're familiar with these concepts, go ahead and start the station. If not, the comms documentation overview is a better place to begin.
You can also follow along with the station's source code, which closely mirrors what you'll see on-screen.
