+As a bind mount is used here, docker will not copy the initial content of the `assets` directory to the mounted directory. 
+You can initialise your assets directory with the content provided in this repository
+```sh
+cp -r /public/assets/* /your/local/assets/
+```

+**Alternatively** if you just want to provide images/icons without customizing the other files (app manifest & pwa icons), you can mount a custom directory in the `www` directory and use it in your `config.yml` for icons path.
