## A small request

I'm trying to reach 1K GitHub stars for "[Bose](https://github.com/omkarcloud/bose)" - an open source bot development framework I just launched for easily creating advanced selenium based bots.
Can you help us out by starring the GitHub repository? It would help us a lot! Thank you! https://github.com/omkarcloud/bose
