+# Feishu (Lark)
+
+Status: beta; inbound via WebSocket using `@larksuiteoapi/node-sdk`.
+
+## Quick setup
+1) Create a Feishu/Lark app and enable the IM message receive event.
+2) Subscribe to `im.message.receive_v1` in your app settings.
+3) Configure `channels.feishu.appId` and `channels.feishu.appSecret`.
+4) Start the gateway.
+
+Minimal config:
+```json5
+{
+  channels: {
+    feishu: {
+      enabled: true,
+      appId: "YOUR_APP_ID",
+      appSecret: "YOUR_APP_SECRET"
+    }
+  }
+}
+```
+
+Multi-account example:
+```json5
+{
+  channels: {
+    feishu: {
+      accounts: {
+        work: { appId: "APP_ID", appSecret: "APP_SECRET" },
+        personal: { appId: "APP_ID", appSecret: "APP_SECRET" }
+      }
+    }
+  }
+}
+```
+
+## How it works
+- Messages are received over the Feishu WebSocket event stream.
+- Replies are sent back to the same `chat_id`.
+- DMs use pairing by default (`channels.feishu.dm.policy`).
+- Group chats can be restricted with `channels.feishu.groupPolicy` and `channels.feishu.groups`.
+
+## Target formats
+- `chat:<chat_id>` for group chats.
+- `user:<open_id>` for direct messages.
+
+## Configuration reference (Feishu)
+- `channels.feishu.appId`: Feishu App ID.
+- `channels.feishu.appSecret`: Feishu App Secret.
+- `channels.feishu.dm.policy`: DM policy (`pairing`, `allowlist`, `open`, `disabled`).
+- `channels.feishu.dm.allowFrom`: allowlist for DMs when policy is `allowlist` or `open`.
+- `channels.feishu.groupPolicy`: `open`, `allowlist`, or `disabled`.
+- `channels.feishu.groups`: per-chat overrides keyed by `chat_id` (supports `requireMention`, `tools`, `users`).
