How to download/install for testing this Module

I am wondering how to download/installing this module for there are no releases for Drupal to find?
Do you still working on it. I am highly interested in a solution to integrate Dolibarr with Drupal either only for Drupal commerce or even better with Drupal as such. The only solution I found so far is via: https://www.drupal.org/project/views_database_connector → 5
Thanks in advance for your hints and feedback about.
