Refresh the About Page and Update Readme under the code folder

[atapas]

The About Page of the app should have the following information,

• GitHub Link to this project
• Twitter link to reach out to, https://twitter.com/tapasadhikary
• Blog link to reach out to, http://blog.greenroots.info/
• Website link to reach out to, https://tapasadhikary.com/

Also, the information should be organized correctly.

The Readme file under the code folder is out of the template. It requires refactoring to align with this project's code.
