-## 📝 Usage
+## Installation
 
-### Installation
+Node.js `24.x` is required.
-
-**Node.js `22.22.3` or newer is required.**
-
-Install the library and the required voice packages:
 
 ```bash
-npm install discord-audio-stream @discordjs/voice prism-media @snazzah/davey opusscript
+npm install discord-audio-stream @discordjs/voice @discordjs/opus
 ```
 
-`libsodium-wrappers` is optional. Install it only when your runtime does not support `aes-256-gcm`:
+Use `opusscript@^0.0.8` only as a slower JavaScript fallback when `@discordjs/opus` cannot be installed.
 
-```bash
+`ffmpeg` must be available either on the host PATH or through the optional `ffmpeg-static` package:
-node -e "console.log(require('node:crypto').getCiphers().includes('aes-256-gcm'))"
-npm install libsodium-wrappers
-```
-
-For bundled ffmpeg support, install `ffmpeg-static` and use `ffmpeg.mode: 'static'`:
 
 ```bash
 npm install ffmpeg-static
 ```
 
-If ffmpeg is already available on the host PATH, use `ffmpeg.mode: 'native'`.
+Use `ffmpeg.mode: 'native'` for PATH-based ffmpeg and `ffmpeg.mode: 'static'` for `ffmpeg-static`.

+## Lifecycle
+
+```ts
+manager.setConnection(connectionOptions);

+await manager.start(); // connect() + play()

+manager.resume();
+await manager.stop(); // stops playback and destroys the voice connection

+
+`connect()` joins the configured voice channel. `play(source?)` starts playback on an existing connection. Use `start()`
+when you want both.

-Default output is raw Discord-compatible PCM: `s16le`, `48000 Hz`, `2 channels`.
 
 You can override ffmpeg arguments through `ffmpeg.inputArgs` and `ffmpeg.outputArgs`. When you override them, you are
 responsible for keeping the output compatible with `StreamType.Raw`.
 
-### Renewal
+Connection renewal is disabled by default because `@discordjs/voice` handles recoverable disconnects. Set
+`renewIntervalMs` only when an application has a measured need for periodic restarts. `stop()` and `dispose()` always
+clear the renewal timer.
 
-By default, the manager schedules a renewal after `5_400_000 ms` so long-running streams can reconnect periodically.
