+# Channels API
+
+The channels API reads, selects, creates, renames, and removes server channels.
+
+## Required Capabilities
+
+| Method | Capability |
+| --- | --- |
+| `channels.list()` | `channels.read` |
+| `channels.select(channelId)` | `channels.read` |
+| `channels.addAudioChannel(request)` | `channels.manage` |
+| `channels.addVideoChannel(request)` | `channels.manage` |
+| `channels.rename(channelId, name)` | `channels.manage` |
+| `channels.remove(channelId)` | `channels.manage` |
+
+## List Channels
+
+```js
+export function activate(context) {
+  const channels = context.api.channels.list();
+
+  context.api.logger.info('Channels', channels.map((channel) => ({
+    id: channel.id,
+    name: channel.name,
+    type: channel.type
+  })));
+}
+```
+
+Example channel list:
+
+```json
+[
+  { "id": "general", "name": "general", "type": "text", "position": 0 },
+  { "id": "support", "name": "support", "type": "text", "position": 1 },
+  { "id": "lobby", "name": "Lobby", "type": "audio", "position": 10 }
+]
+```
+
+## Select a Channel
+
+```js
+export function activate(context) {
+  context.api.channels.select('support');
+}
+```
+
+## Add a Voice Channel
+
+```js
+export function activate(context) {
+  context.api.channels.addAudioChannel({
+    id: 'raid-voice',
+    name: 'Raid Voice',
+    position: 20
+  });
+}
+```
+
+## Add a Video Channel Section
+
+```js
+export function activate(context) {
+  context.api.channels.addVideoChannel({
+    id: 'watch-party-video',
+    name: 'Watch Party',
+    position: 30
+  });
+}
+```
+
+## Rename and Remove
+
+```js
+export function activate(context) {
+  context.api.channels.rename('raid-voice', 'Raid Voice - Tonight');
+  context.api.channels.remove('old-event-room');
+}
+```
+
+Channel creation, rename, and removal should be user-confirmed because they change the shared server structure.
