FYI: This should be fairly simple to implement from a technical viewpoint, in fact the todo tasks user can switch between english and german and changes in code are shown in both english and german version are already implemented. So once the translated content is put into the content/_english folder with the same names, the website will automatically extend the language switcher on the bottom of the menu.

The code itself has been included as a Git submodule and Dependabot will auto-update it whenever new code gets pushed to the pi4j-example-crowpi repository, e.g. #24 - so code changes are automatically reflected in the docs.
