+# Docker file to create an image that contains enough software to listen to events on the 433,92 Mhz band,
+# filter these and publish them to a MQTT broker.
+#
+# The script resides in a volume and should be modified to meet your needs.
+#
+# The example script filters information from weather stations and publishes the information to topics that
+# Domoticz listens on.
+#
+# Special attention is required to allow the container to access the USB device that is plugged into the host.
+# The container needs priviliged access to /dev/bus/usb on the host.
+# 
+# docker run --name rtl_433 -d -e MQTT_HOST=<mqtt-broker.example.com>   --privileged -v /dev/bus/usb:/dev/bus/usb  <image>
