The project schul-frei in general and AlekSIS specifically are open for anybody. Take part in development on our GitLab instance EduGit or join our project chatroom. Everyone is welcome to help us to make schul-frei more competitive. Visit schul-frei.dev to get more information.
Our goal is to create a network of hackers, teachers and IT companies. IT companies can help to bring FOSS to schools, if they offer commercial support which for example schools can use.
