+summary: "Program receives and decodes WMBus telegrams"
+description: |
+  The program receives and decodes C1, T1 or S1 telegrams
+  (using the wireless mbus protocol) to acquire utility meter readings.
+  The readings can then be published using MQTT, curled to a REST api,
+  inserted into a database or stored in a log file.
+  Following must be executed "sudo snap connect wmbusmeters:raw-usb core:raw-usb"
+  to allow snap read USB devices and check that root user of your system is 
+  added to group that can read USB devices
