+# Create a docker image for the RPI
+# Build the docker image from the root of the project with the following command :
+# $ docker build -t librespot-rpi -f .\contrib\Dockerfile.Rpi .
+#
+# This builds a docker image which is usable when running docker on the rpi.
+# 
+# This Dockerfile builds in windows without any requirements, for linux based systems you might need to run the following line:
+# docker run --rm --privileged multiarch/qemu-user-static:register --reset
+# (see here for more info: https://gist.github.com/PieterScheffers/d50f609d9628383e4c9d8d7d269b7643 )
+#
+# Save the docker image to a file:
+# $ docker save -o contrib/librespot-rpi librespot-rpi
+#
+# Move it to the rpi and import it with:
+# docker load -i librespot-rpi
+#
+# Run it with:
+# docker run -d --restart unless-stopped $(for DEV in $(find /dev/snd -type c); do echo --device=$DEV:$DEV; done) --net=host --name librespot-rpi librespot-rpi --name {devicename}
