 Since MBusPico v2.0 there is also a Python version available. Including a ready-made Python docker container running MBusPico.
 
 This enables the usage of MBusPico application on your RaspberryPi already running [LoxBerry](https://github.com/mschlenstedt/Loxberry).
 
-After installing the [Loxberry Docker Plugin](https://wiki.loxberry.de/plugins/docker/start) you can run the MBusPico docker container with the following settings:
+## Enable serial port
+
+On an generic Raspberry Pi (for example running Raspian) execute  `sudo raspi-config` and enable the serial port in 
+`(3) Interface options` -> `(I6) Serial Port`. Just enable the serial port and do not enable the console on it.
+Afterwards reboot the device.
+
+On a Loxberry this can be done directly in the web UI. From `System settings` select `Loxberry services` and `More options`:

+
+## Loxberry
 
+Install the [Loxberry Docker Plugin](https://wiki.loxberry.de/plugins/docker/start). In the portainer web UI you can create 
+a MBusPico docker container from `Containers` and hit the `Add container` button.
+
+Make sure that you set some mandatory options:
+
+* the `Network mode` must be `host`
+* the serial port `device` (in most cases `/dev/ttyS0`) must be mapped to the docker container
+* MBusPico options (like at least the decryption key `MBUSPICO_DEVICE_KEY`) can be set via `environment variables`
+
+## Running manually
+
+Extract the `python.zip` archive of an MBusPico release and execute it directly with Python:
+```sh
+cd /path/to/extracted
+python3 main.py
+```
+
+Example docker run call:
+```sh
+docker run --name MBusPico \
+	--network host \
+	--device=/dev/ttyS0 \
+	-e MBUSPICO_DEVICE_KEY=XXXXXXXXXXXXXXXXXXXX \
+	-e MBUSPICO_HTTP_SERVER_PORT=8080 \
+	-e MBUSPICO_HTTP_ENABLED=1 \
+	-e MBUSPICO_SERIAL_PORT=/dev/ttyS0 \
+	ravenworx/mbuspico:latest
