-### Contaner automated build
-
-The project complies with the scripting based [Dockerfile](https://docs.docker.com/engine/reference/builder/) method to build the image output file. Using this method is a precondition for an [automated](https://docs.docker.com/docker-hub/builds/) web based build process on DockerHub platform.
-
-DockerHub web platform is x86 CPU based, but an ARM CPU coded output file is needed for Raspberry Pi systems. This is why the Dockerfile includes the [balena.io](https://balena.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/) steps.
