 # Using Docker
 
-~~~
-docker build --tag <imagename>
-cd <workdir>
+The docker image is built automatically from the current master branch.
+You can use the following commands to set up the docker container:
+
+Create a directory for static and config files:
+```
 mkdir -p run/{log,static,config}
-cp <original_dir>/bitpoll/settings_local.py run/config/settings.py
-vim run/config/settings.py
-docker run -a stdout -a stderr --rm --name bitpoll -p 3008:3008 -p 3009:3009 --volume `pwd`/run/static:/opt/static --volume `pwd`/run/config:/opt/config --volume `pwd`/run/log/:/opt/log <image_name>
-~~~
-The Static assets from <workdir>/run/static have to be served from the Webserver at /static/.
-The Container listens for uwsgi traffic on Port 3008 and for HTTP traffic on Port 8009
+```
+
+Get the example settings file and adapt it according to your needs:
+```
+wget https://raw.githubusercontent.com/fsinfuhh/Bitpoll/master/bitpoll/settings_local.sample.py -O run/config/settings.py
+```
+
+Start the docker container:
+```
+docker run -a stdout -a stderr --rm --name bitpoll -p 3008:3008 -p 3009:3009 --volume ./run/static:/opt/static --volume ./run/config:/opt/config ghcr.io/fsinfuhh/bitpoll
+```
+
+The Static assets from `run/static` have to be served from the Webserver at `/static/`.
+The Container listens for uwsgi traffic on Port 3008 and for HTTP traffic on Port 8009.
