 All the Dockerfile does is copy your custom plugins gemfile into the image, install the gems and precompile any new assets.

+If you are using the `-slim` tag you will need to do the following to add your plugin.

+# COPY /path/to/my/local/openproject-slack /app/vendor/plugins/openproject-slack
+
+COPY Gemfile.plugins /app/

 **4. Build the image**
 
 To actually build the docker image run:
 
 ```shell
-docker build -t openproject-with-slack .
+docker build --pull -t openproject-with-slack .
 ```
 
 The `-t` option is the tag for your image. You can choose what ever you want.
