Blog hosted with Hydeout theme not showing post

I have created a site here: https://pchaturv.github.io/Praveen/ and posted some post under _post folder but nothing is showing up. I downloaded the theme and after modification uploaded to my repository. 

Any help is highly appreciated. I am new to Jekyell and Ruby so doesn’t have much knowledge about how things works. Thanks for your help.
