 If you are using [Docker](https://www.docker.com/), you can compile Hyperion inside a docker container. This keeps your system clean and with a simple script it's easy to use. Supported is also cross compiling for Raspberry Pi (Debian Stretch or higher). To compile Hyperion just execute one of the following commands.
 
 The compiled binaries and packages will be available at the deploy folder next to the script.<br/>
-Note: call the script with `./docker-compile.sh -h` for more options
