How to cite the use of Photon?

[waeiski]

Hey,

I've been working on a dataset, which will eventually be published as an open dataset. In production of the dataset, we've been geocoding place names with Photon through geopy, and I was wondering is there a way to cite Photon? I could not find such information anywhere on GitHub or the main web page, nor could I find any academic articles that would have done so. Regardless, I want to give credit where it's due.

If somebody out there has the BibTeX or some such for such an occasion like this, I would really appreciate it!

Thanks!
