-## Flashblocks Websocket Proxy
+# Flashblocks Websocket Proxy
+
+## Overview
+The Flashblocks Websocket Proxy is a service that subscribes to new Flashblocks from
+[rollup-boost](https://github.com/flashbots/rollup-boost) on the sequencer. Then broadcasts them out to any downstream 
+RPC nodes. Minimizing the number of connections to the sequencer and restricting access.
+
+> ⚠️ **Warning**
+> 
+> This is currently alpha software -- deploy at your own risk!
+> 
+> Currently, this project is a one-directional generic websocket proxy. It doesn't inspect any data or validate clients.
+> This may not always be the case.
+
+## For Developers
