Fix some small mistakes in the README and add some hyperlinks

[aflah02]

In the README there are some minor mistakes such as spelling or grammar which I can fix.
Secondly I propose adding links for the technologies being used so people can access them quickly.
I can work on this

@aflah02 Go for it, could you also maybe move the section from here till here in the CONTRIBUTING.md file?

[aflah02]

@kunal-kushwaha yeah sure i'll do that

[aflah02]

@kunal-kushwaha I've done this thrice already it works and then some other requests get merged and a conflict ensues.

@kunal-kushwaha can I work on this?
