The install.txt need to be updated and rewritten in english
May I suggest that you also make it more clear on how to actually get a (test?) dataset?
But no datasets are to be found on that page - it's kind of a circular reference as it links back here?
I don't see any datasets included in this project - nor the Drupal project?
You are right. The project needs better documentation, but it's not actively maintained at the moment. Sorry.
Send me a mail, if you need assistance.
