Update README

[0xRampey]

Make README more informative and interesting.
Perhaps we can use this template: https://gist.github.com/prampey/aa67a1bfb7fae2d567be8b6cfa4e868e

https://www.gitbook.com/ can be good inspiration for writing a brief document summarising our project to make the job easier for future devs

[sharanry]

So are we implementing the one in gist or gitbook?

[0xRampey]

The Wiki can handle our current documentation. We'll migrate later to GitBook when the need arises.

Great job @sharanry !
I think it's better if we add a link to Wiki under the Contributing section. Also, this is an 'isomorphic web application'. I'll be making some changes.
