Is there an option to donate to this project?

Hello @vpj @nmasnadithya @lakshith-403 ! 
Awesome job creating this awesome project. I would like to make a small donation to this initiative as I found this quite helpful a few years ago. I couldn't do it at that time but I can do now. Maybe I am forgetting but I thought you guys had an option for sponsorship few years ago but the option is no longer there?
