+# @openclaw/twitch
+
+Twitch channel plugin for OpenClaw.
+
+## Install (local checkout)
+
+```bash
+openclaw plugins install ./path/to/local/twitch-plugin
+```
+
+## Install (npm)
+
+```bash
+openclaw plugins install @openclaw/twitch
+```
+
+Onboarding: select Twitch and confirm the install prompt to fetch the plugin automatically.
+
+## Config
+
+Minimal config (simplified single-account):
+
+**⚠️ Important:** `requireMention` defaults to `true`. Add access control (`allowFrom` or `allowedRoles`) to prevent unauthorized users from triggering the bot.
+
+```json5
+{
+  channels: {
+    twitch: {
+      enabled: true,
+      username: "openclaw",
+      accessToken: "oauth:abc123...", // OAuth Access Token (add oauth: prefix)
+      clientId: "xyz789...", // Client ID from Token Generator
+      channel: "vevisk", // Channel to join (required)
+      allowFrom: ["123456789"], // (recommended) Your Twitch user ID only (Convert your twitch username to ID at https://www.streamweasels.com/tools/convert-twitch-username-to-user-id/)
+    },
+  },
+}
+```
+
+**Access control options:**
+
+- `requireMention: false` - Disable the default mention requirement to respond to all messages
+- `allowFrom: ["your_user_id"]` - Restrict to your Twitch user ID only (find your ID at https://www.twitchangles.com/xqc or similar)
+- `allowedRoles: ["moderator", "vip", "subscriber"]` - Restrict to specific roles
+
+Multi-account config (advanced):
+
+```json5
+{
+  channels: {
+    twitch: {
+      enabled: true,
+      accounts: {
+        default: {
+          username: "openclaw",
+          accessToken: "oauth:abc123...",
+          clientId: "xyz789...",
+          channel: "vevisk",
+        },
+        channel2: {
+          username: "openclaw",
+          accessToken: "oauth:def456...",
+          clientId: "uvw012...",
+          channel: "secondchannel",
+        },
+      },
+    },
+  },
+}
+```
+
+## Setup
+
+1. Create a dedicated Twitch account for the bot, then generate credentials: [Twitch Token Generator](https://twitchtokengenerator.com/)
+   - Select **Bot Token**
+   - Verify scopes `chat:read` and `chat:write` are selected
+   - Copy the **Access Token** to `token` property
+   - Copy the **Client ID** to `clientId` property
+2. Start the gateway
