-# P2P Poll App
+# 🗳️ Simple P2P Poll & Chat
+
+This is a minimal prototype of a decentralized governance tool built for the **Demcode Evocracy** experiment. It allows for basic deliberation and voting without a central database or server-side logic.
+
+## What it does
+- **P2P Connectivity:** Uses WebRTC (via PeerJS) to link browsers directly.
+- **Mesh-capable:** Allows multiple connections to sync the same poll state.
+- **Live Sync:** Changes to the poll topic, options, or votes are broadcast to all connected peers.
+- **Chat:** A simple sidebar to discuss the poll in real-time.
+
+## How to use it
+1. Open the page: [https://andrewlehr.github.io/evocracy-p2p-poll/]
+2. Set your **Nickname** and click "Set".
+3. Share your nickname with a friend.
+4. One person enters the other's nickname in the **Connect** box and clicks "Add Peer".
+5. Once connected, you can set a topic, add options, and vote.
+
+## Technical Notes
+- **Data Persistence:** There is no database. If everyone closes their browser, the data is lost.
+- **Networking:** It uses a public signaling server to find peers, but the actual data (votes/chat) stays between the browsers.
+- **Conflict Handling:** Uses a simple "Last Write Wins" broadcast to keep peers in sync.
+
+## Transparency
+This code was generated with the assistance of **Gemini (Google AI)** to quickly prototype the WebRTC networking logic. The goal was to create a clean, readable foundation that is easy for others to merge or modify during the next phase of the experiment.
