+CraftBeerPi 4 is an open source software solution to control the brewing and
+fermentation of beer :beer:.
+
+## 📚 Documentation
+Instructions on how to install CraftBeerPi and use its plugins is described
+in the documentation, that can be found here: [gitbook.io](https://openbrewing.gitbook.io/craftbeerpi4_support/).
+
+### Plugins
+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.
