-# ⚠️ Moved to [git.methanium.net](https://git.methanium.net/tensamin/omikron) ⚠️
+# Omikron
+The Omikron is a reverse proxy and relay server for Tensamin.
+It's primary purpose is to connect you're client to your Iota & hide your IP and service usage.
+The Omikron also host Voice-Calls.
+
+The Omikron is only used when the Iota is in Centralized and Hybrid mode, or when the Client uses the Tensamin Client with default configuration.
