+
+2) Create `config.yaml`.
 
 ``` bash
 extension_thumbnail: "_thumbnail.mp4"
 width_thumbnail: 600
 path_videos: "videos"
+audio_quality_thumbnail: 128
 ```
 
-2) Make folder `path_videos`.
+3) Make folder `path_videos`.
 
 ``` bash
 mkdir videos
 ```
 
-3) Install `ffmpeg`.

-5) Now you can execute.
+6) Now you can execute.
 
 ``` bash

-6) Leave videos.
+or
 
-Everything you leave in the videos folder will be optimized for web with the specified resolution (600 px in this example).
+``` bash
