Setup CI/CD for the repository

I had a trial of setting up CI/CD in the forked branch [1]. The pipeline seems to work [2]. The temporary deployed skeleton can be found here [3].

The question I have is can we have a project eos area to host the document? Like in the example [4] I followed. @spigazzi Do you know if this is possible?
