+Multi-bot support is available for `whatsapp`, `telegram`, `discord`, `feishu`, `mochat`,
+`dingtalk`, `slack`, `email`, `qq`, `matrix`, and `wecom`.
+Use `instances` when you want more than one bot/account for the same channel; each instance is
+routed as `channel/name`.
+
+```json
+{
+  "channels": {
+    "telegram": {
+      "enabled": true,
+      "instances": [
+        {

+        }
+      ]
+    }
+  }
+}
+```
+
+For `whatsapp`, each instance should point to its own bridge process with its own `bridgeUrl`
+and bridge auth/session directory.
+
+Multi-instance notes:
+
+- Keep each `instances[].name` unique within the same channel.
+- Single-instance config is still supported; switch to `instances` only when you need multiple
+  bots/accounts for the same channel.
+- Replies, sessions, and routing use `channel/name`, for example `telegram/main` or `qq/bot-a`.
+- `matrix` instances automatically use isolated `matrix-store/<instance>` directories.
+- `mochat` instances automatically use isolated runtime cursor directories.
+- `whatsapp` instances require separate bridge processes, typically with different `BRIDGE_PORT`
+  and `AUTH_DIR` values.

-# Channel Plugin Guide
-
-Build a custom nanobot channel in three steps: subclass, package, install.
-
-## How It Works
-
-nanobot discovers channel plugins via Python [entry points](https://packaging.python.org/en/latest/specifications/entry-points/). When `nanobot gateway` starts, it scans:
-
-1. Built-in channels in `nanobot/channels/`
-2. External packages registered under the `nanobot.channels` entry point group
-
-If a matching config section has `"enabled": true`, the channel is instantiated and started.
-
-## Quick Start
-
-We'll build a minimal webhook channel that receives messages via HTTP POST and sends replies back.
-
-### Project Structure
-
-```

-│   ├── __init__.py          # re-export WebhookChannel
-│   └── channel.py           # channel implementation

-### 1. Create Your Channel

-
-__all__ = ["WebhookChannel"]

-
-### 2. Register the Entry Point
-
-```toml
-# pyproject.toml
-[project]
-name = "nanobot-channel-webhook"
-version = "0.1.0"
-dependencies = ["nanobot", "aiohttp"]
-
-[project.entry-points."nanobot.channels"]
-webhook = "nanobot_channel_webhook:WebhookChannel"
-
-[build-system]
-requires = ["setuptools"]
-build-backend = "setuptools.backends._legacy:_Backend"
-```
-
-The key (`webhook`) becomes the config section name. The value points to your `BaseChannel` subclass.
-
-### 3. Install & Configure
-
-```bash
-pip install -e .
-nanobot plugins list      # verify "Webhook" shows as "plugin"
-nanobot onboard           # auto-adds default config for detected plugins
-```
-
-Edit `~/.nanobot/config.json`:
-
-```json
-{
-  "channels": {
-    "webhook": {
-      "enabled": true,
-      "port": 9000,
-      "allowFrom": ["*"]
-    }
-  }
-}
-```
-
-### 4. Run & Test
-
-```bash
-nanobot gateway
-```
-
-In another terminal:
-
-```bash
-curl -X POST http://localhost:9000/message \
-  -H "Content-Type: application/json" \
-  -d '{"sender": "user1", "chat_id": "user1", "text": "Hello!"}'
-```
-
-The agent receives the message and processes it. Replies arrive in your `send()` method.
-
-## BaseChannel API
-
-### Required (abstract)
-
-| Method | Description |
-|--------|-------------|
-| `async start()` | **Must block forever.** Connect to platform, listen for messages, call `_handle_message()` on each. If this returns, the channel is dead. |
-| `async stop()` | Set `self._running = False` and clean up. Called when gateway shuts down. |
-| `async send(msg: OutboundMessage)` | Deliver an outbound message to the platform. |
-
-### Provided by Base
-
-| Method / Property | Description |
-|-------------------|-------------|
-| `_handle_message(sender_id, chat_id, content, media?, metadata?, session_key?)` | **Call this when you receive a message.** Checks `is_allowed()`, then publishes to the bus. |
-| `is_allowed(sender_id)` | Checks against `config["allowFrom"]`; `"*"` allows all, `[]` denies all. |
-| `default_config()` (classmethod) | Returns default config dict for `nanobot onboard`. Override to declare your fields. |
-| `transcribe_audio(file_path)` | Transcribes audio via Groq Whisper (if configured). |
-| `is_running` | Returns `self._running`. |
-
-### Message Types
-
-```python
-@dataclass
-class OutboundMessage:
-    channel: str        # your channel name
-    chat_id: str        # recipient (same value you passed to _handle_message)
-    content: str        # markdown text — convert to platform format as needed
-    media: list[str]    # local file paths to attach (images, audio, docs)
-    metadata: dict      # may contain: "_progress" (bool) for streaming chunks,
-                        #              "message_id" for reply threading
-```
-
-## Config
-
-Your channel receives config as a plain `dict`. Access fields with `.get()`:
-
-```python
-async def start(self) -> None:
-    port = self.config.get("port", 9000)
-    token = self.config.get("token", "")
-```
-
-`allowFrom` is handled automatically by `_handle_message()` — you don't need to check it yourself.
-
-Override `default_config()` so `nanobot onboard` auto-populates `config.json`:
-
-```python
-@classmethod
-def default_config(cls) -> dict[str, Any]:
-    return {"enabled": False, "port": 9000, "allowFrom": []}
-```
-
-If not overridden, the base class returns `{"enabled": false}`.
-
-## Naming Convention
-
-| What | Format | Example |
-|------|--------|---------|
-| PyPI package | `nanobot-channel-{name}` | `nanobot-channel-webhook` |
-| Entry point key | `{name}` | `webhook` |
-| Config section | `channels.{name}` | `channels.webhook` |
-| Python package | `nanobot_channel_{name}` | `nanobot_channel_webhook` |
-
-## Local Development
-
-```bash
-git clone https://github.com/you/nanobot-channel-webhook
-cd nanobot-channel-webhook
-pip install -e .
-nanobot plugins list    # should show "Webhook" as "plugin"
-nanobot gateway         # test end-to-end
-```
-
-## Verify
-
-```bash
-$ nanobot plugins list
-
-  Name       Source    Enabled
-  telegram   builtin  yes
-  discord    builtin  no
-  webhook    plugin   yes
-```
