+This app is already compatible with Render because it uses a dynamic port (`process.env.PORT`) and Socket.IO over a Node web service.
+
+1. Push your latest code to GitHub.
+2. Go to https://render.com and sign in with GitHub.
+3. Click **New +** → **Web Service**.
+4. Choose **Build and deploy from a Git repository** and select this repo.
+5. Configure service settings:
+   - **Runtime:** `Node`
    - **Build Command:** `npm install`
    - **Start Command:** `npm start`
-5. Deploy and get free `.onrender.com` HTTPS URL
+   - **Plan:** `Free`
+   - **Region:** nearest to your users
+6. Add environment variables from your local `.env` file (never commit secrets):
+   - `DATABASE_URL`
+   - `JWT_SECRET`
+   - `CORS_ORIGIN` (set to your frontend URL or `*` for quick testing)
+   - Optional TURN variables for WebRTC: `TURN_URLS`, `TURN_USERNAME`, `TURN_CREDENTIAL`
+7. Click **Create Web Service** and wait for build logs to finish.
+8. Open your live URL: `https://<your-service>.onrender.com`
+9. Validate health endpoint in browser:
+   - `https://<your-service>.onrender.com/api/version`
+10. Test real-time chat from 2 browser tabs/devices.
+
+Notes for Render Free tier:
+- Free services sleep after inactivity; first wake-up request can take around 30-60 seconds.
+- This app uses PostgreSQL via `DATABASE_URL`, so chat/account data is persisted in DB, not only in memory.
+- Do not set `PORT` manually on Render; Render injects it automatically.
 
 ####  Option 3: Self-host with proper domain (Advanced)
