+**Where to find these values:**
+
+- **`OPENAI_API_KEY`** — from [platform.openai.com/api-keys](https://platform.openai.com/api-keys). If you already have the Conversation app installed, you can copy the key from its `.env` file (same parent directory, under `conversation_venv`).
+- **`OPENCLAW_TOKEN`** — your gateway auth token, found in `~/.openclaw/openclaw.json` under `gateway.auth.token`.
+- **`OPENCLAW_GATEWAY_URL`** — defaults to `ws://localhost:18789` if OpenClaw runs on the same machine.
+
 That's it — launch ReachyClaw from the app and it will work.
