How to get started

In addition to the source code repositories, there is also a dedicated 'compose'-repository which contains a development environment, build pipelines and deployment instructions. The general purpose version of didmos V2 is called didmos2-demo and its compose-repository is accessible here:

In there you can find details on how to setup a development environment, which currently is only fully documented for Fedora operating systems.
