I messed up the repo and took it down until I fix it up. Wheel based install should be enough to take it for a spin. If you need any details feel free to ping me.

Possible to do pip install from Git repository?
E.g : pip install git+https://github.com/….

At the moment the two installation options are:

pip install dejan
https://pypi.org/project/dejan/

or download the wheels:
