-## Usage
+## Quick Start (Downloading Videos)
 
+`untube` provides a readable stream that you can pipe anywhere (e.g., to a file, to `fluent-ffmpeg`, or an HTTP response).
+
+> **⚠️ Important Note on Video & Audio:**  
+> YouTube separates high-quality video (1080p, 4K) and audio into different streams (DASH formats). If you choose a high-quality video format (like `highestvideo`), the resulting file will **not have sound**. If you want a single file with both high-quality video and audio, you must download the video and audio streams separately and merge them yourself using a tool like `ffmpeg`.
+
 ```typescript
-import { getVideoInfo } from 'untube';
+import fs from 'node:fs';
+import untube from 'untube';
 
-async function main() {
-    try {
-        const info = await getVideoInfo('videoId', {
-            // Optional: Path to cookies file (Netscape format) or RawCookie object
-            cookie: './cookies.txt',
-            // Optional: Use proxy to avoid rate limits or blocks
-            proxy: 'http://user:[e-mail]:8080'
-        });
+// Setup AbortController to cancel download if needed
+const controller = new AbortController();
 
-        console.log('Title:', info.title);
-        console.log('Channel:', info.uploader);
-        
-        // List available video & audio formats
-        info.formats.forEach(format => {
-            console.log(`[${format.format_id}] ${format.resolution} - ${format.url}`);

+## Configuration Options
+
+When calling `untube(id, options)` or `untube.getVideoInfo(id, options)`, you can pass an options object.
+
+### `format` (Quality Selection)
+You can easily pick the desired quality using preset strings or specific format IDs (`itag`):
+
+- **Presets:** `'highest'` (default), `'lowest'`, `'highestaudio'`, `'lowestaudio'`, `'highestvideo'`, `'lowestvideo'`.
+- **Resolutions:** `'1080p'`, `'720p'`, etc.
+- **Format ID / itag:** Use specific itags like `'137'` (1080p video-only), `'140'` (m4a audio), or `'18'` (360p video+audio).
+
+```typescript
+// Download exactly 1080p MP4 (Video only)
+untube('videoId', { format: '137' });
+
+// Download the best audio available
+untube('videoId', { format: 'highestaudio' });
+```
+
+### `mode` (Streaming Behavior)
+By default, `untube` uses **parallel** downloading to bypass YouTube bandwidth throttling. 
+
+| Mode | Characteristics | Best for |
+| :--- | :--- | :--- |
+| `'parallel'` (Default) | Incredibly fast. Downloads chunks concurrently into a temp file and streams the result. Emits `progress` events. | Downloading files, massive scrapers. |
+| `'sequential'` | Pure RAM streaming. Slower (throttled by YouTube). No temp files used. Start-up time is instant. | Real-time audio playback. |
+
+```typescript
+// Use sequential mode for instant start-up time
+const stream = untube('videoId', { format: 'highestaudio', mode: 'sequential' });
+```
+
+---
+
+## Fetching Metadata
+
+If you only need the video details without downloading the stream, use `untube.getVideoInfo()`:
+
+```typescript
+import untube from 'untube';
+
+const info = await untube.getVideoInfo('videoId');
+
+console.log('Title:', info.title);
+console.log('Views:', info.view_count);
+```
+
+### Format Utilities
+
+`untube` includes powerful utility functions to help you manage and filter formats from the `info` object.
+
+```typescript
+const info = await untube.getVideoInfo('videoId');
+
+// 1. Choose a specific format manually
+const bestAudio = untube.chooseFormat(info.formats, { quality: 'highestaudio' });
+
+// 2. Filter formats custom logic
+const mp4Only = untube.filterFormats(info.formats, format => format.container === 'mp4');
+
+// 3. Filter using presets ('video', 'audio', 'audioandvideo', 'videoonly', 'audioonly')
+const videoNoSound = untube.filterFormats(info.formats, 'videoonly');
+
+// 4. Sort formats from highest to lowest quality
+const sorted = untube.sortFormats(info.formats);
+```
