 Plugins extend the base functionality of CraftBeerPi 4.
 You can find a list of available plugins [here](https://openbrewing.gitbook.io/craftbeerpi4_support/master/plugin-installation#plugin-list).
 
-### Docker image
-While CraftbeerPi is primarily created to be run on a RaspberryPi
-you can also use a docker image to run it. This let's you try CraftBeerPi
-quickly without much installation overhead. It can also be very handy
-when developing your own plugins.
-
-Images are currently available for `arm64` and `amd64` architectures.
-That means, that they won't run on a RaspberryPi unless you installed
-a 64bit version of the OS. This is only a requirement for the docker image,
-not if you install CraftBeerPi on the pi directly.
-
-### Start a container
-You can also use the image in your real setup with docker or docker-compose (or other orchestrators).
-
-```bash
-# setup the configuration directory for later use in a volume mount (must be done once)
-mkdir config && chown :1000 config
-docker run --rm -v "$(pwd)/config:/cbpi/config" ghcr.io/avollkopf/craftbeerpi4:latest cbpi setup
-
-# run craftbeerpi
-docker run -d -v "$(pwd)/config:/cbpi/config" -p 8000:8000 ghcr.io/avollkopf/craftbeerpi4:latest
-```
-
-or as compose file
-```yml
-version: "3.7"
-services:
-  craftbeerpi:
-    image: ghcr.io/avollkopf/craftbeerpi4:latest
-      volumes:
-        - "./config:/cbpi/config"
-      ports:
-        - 8000:8000
-```
-
-Please note that this setup does not include GPIO functionality for CraftBeerPi 4.
-You may be lucky with one of the methods described here to get it to work:

-
-#### Install plugins in the container
-You can create your own image based on `ghcr.io/avollkopf/craftbeerpi4` and install
-plugins as `RUN` commands in the docker file as you would in a regular environment.
-
-Sample `Dockerfile`
-```Dockerfile
-FROM ghcr.io/avollkopf/craftbeerpi4:vXX.XX.XX.XX
-
-# Switch to root user for installing plugins
-USER root
-
-# Install plugins
-RUN pip3 install --no-cache-dir cbpi4-pt100x
-
-# Don't forget to switch back to craftbeerpi user
-USER craftbeerpi
-
-# Add plugin to craftbeerpi
-RUN cbpi add cbpi4-pt100x
-```
-Then build the image
-```bash
-docker build . -t yourimagename
-```
-Then build and use your image in the `docker run` command or `docker-compose` file.
