Prerequisites: All you need to use it is Chrome/Chromium.

Note: I am not involved with the currently development team. Checked their code, found it awesome and so Open Sourced it for the benefit of community. It has no intention in taking credit of their work or any other gains. It is purely for educational purpose only
