Update README?

[SpaceWhite]

Hi guys

Securitylab readme provides very little information about the detail of this repository
Don't you guys think adding more details on the readme would be great?

Hey @SpaceWhite
We'll soon transform this README into something more useful.
I cannot spoil the surprise, you'll have to 👀 it.
