 If your host is running any kind of flash-based storage (e.g. SSDs or the SD-card of a Raspberry Pi) it is highly recommended to offload the temporary files to memory-based storage. you can do this by adding `--tmpfs=/tmp/openwebrx` to the docker commandline. Please note that this is not just an example, the path matches the container setup. If you wish to use a different path, you will need to update the container configuration.
 
 This setup allows modification of all settings in the web configuration. If you wish to modify any settings in the configuration files in `/etc/openwebrx`, please set up an additional volume and mount for `/etc/openwebrx`.
