Changed the purpose of the site in the README

https://github.com/mdabydeen/ad-web-project/issue/2001

The is just a dummy message to show how a really really long commit
message works. The things that changed were:

* README now shows the purpose of the document
* User have a clearer meaning of what the hell is going on.
* All of this is really just wasting your time.
* Everything above is unnecessary
