+
+PicoClaw can connect to WhatsApp in two ways:
+
+- **Native (recommended):** In-process using [whatsmeow](https://github.com/tulir/whatsmeow). No separate bridge. Set `"use_native": true` and leave `bridge_url` empty. On first run, scan the QR code with WhatsApp (Linked Devices). Session is stored under your workspace (e.g. `workspace/whatsapp/`). The native channel is **optional** to keep the default binary small; build with `-tags whatsapp_native` (e.g. `make build-whatsapp-native` or `go build -tags whatsapp_native ./cmd/...`).
+- **Bridge:** Connect to an external WebSocket bridge. Set `bridge_url` (e.g. `ws://localhost:3001`) and keep `use_native` false.
+
+**Configure (native)**
+
+```json
+{
+  "channels": {
+    "whatsapp": {
+      "enabled": true,
+      "use_native": true,
+      "session_store_path": "",
+      "allow_from": []
+    }
+  }
+}
+```
+
+If `session_store_path` is empty, the session is stored in `&lt;workspace&gt;/whatsapp/`. Run `picoclaw gateway`; on first run, scan the QR code printed in the terminal with WhatsApp → Linked Devices.

+# Troubleshooting
+
+## "model ... not found in model_list" or OpenRouter "free is not a valid model ID"
+
+**Symptom:** You see either:
+
+- `Error creating provider: model "openrouter/free" not found in model_list`
+- OpenRouter returns 400: `"free is not a valid model ID"`
+
+**Cause:** The `model` field in your `model_list` entry is what gets sent to the API. For OpenRouter you must use the **full** model ID, not a shorthand.
+
+- **Wrong:** `"model": "free"` → OpenRouter receives `free` and rejects it.
+- **Right:** `"model": "openrouter/free"` → OpenRouter receives `openrouter/free` (auto free-tier routing).
+
+**Fix:** In `~/.picoclaw/config.json` (or your config path):
+
+1. **agents.defaults.model** must match a `model_name` in `model_list` (e.g. `"openrouter-free"`).
+2. That entry’s **model** must be a valid OpenRouter model ID, for example:
+   - `"openrouter/free"` – auto free-tier
+   - `"google/gemini-2.0-flash-exp:free"`
+   - `"meta-llama/llama-3.1-8b-instruct:free"`
+
+Example snippet:
+
+```json
+{
+  "agents": {
+    "defaults": {
+      "model": "openrouter-free"
+    }
+  },
+  "model_list": [
+    {
+      "model_name": "openrouter-free",
+      "model": "openrouter/free",
+      "api_key": "sk-or-v1-YOUR_OPENROUTER_KEY",
+      "api_base": "https://openrouter.ai/api/v1"
+    }
+  ]
+}
