I have some questions to configure this repo to run on my side.

Hi!, Rana
Thanks for your effort on this repository.
I am feeling this project is very suitable for my purpose on dev part.
So I just cloned this repo and tried your readme but as I am a absolutely newbee in this part, so I am feeling trouble going on.
Specially google-services.json file configuration and map fragment integration where and how.
Please guide me more in depth.
Best Regards.
