-## ffmpeg and ffprobe
+## Configuration
 
 The functionalities to render and analyze videos rely on [ffmpeg](https://ffmpeg.org/)
 and [ffprobe](https://ffmpeg.org/ffprobe.html).
 
+On Linux, you can try
+
+```sh
+sudo apt-get update && sudo apt-get install ffmpeg
+```
+
 Make sure these tools are installed locally and available in your PATH,
 or configure the `FFMPEG_PATH` / `FFPROBE_PATH` environment variables to point to the `ffmpeg`/`ffprobe` executable.
