You should use screenshots instead of a camera. Apart from that, nice tutorial. Also, you might want to include the setup in your tutorial; like, how to setup the environment in Windows.

Thanks a lots. I will edit the post to include that. The reason I had used a camera was because I am posting from my phone, but those were older pictures I had taken. But you are right and I'll use better pictures whenever I can.
