+If you'd like to use a customized `config.json`, you can follow the steps in [Basic Usage](https://docs.webp.sh/usage/basic-usage/) to genereate one, and mount it into the container's `/etc/config.json`, example `docker-compose.yml` as follows:

 * [WebP Cloud](https://docs.webp.se/webp-cloud/)
-  * No need to install WebP Server Go, especially suitable for static websites.
-  * Image Conversion: WebP Cloud converts images to WebP format, reducing size while maintaining quality for faster website loading.
-    * Example: Original image URL (https://yyets.dmesg.app/api/user/avatar/Benny) becomes compressed URL (https://vz4w427.webp.ee/api/user/avatar/Benny).

   * Caching: WebP Cloud automatically caches served images, reducing traffic and bandwidth load on the origin server.
