Explain the app

The index.html at https://github.com/agnelvishal/notepad/blob/master/index.html needs to be updated to tell that the app is about to users.

Try this app at https://sarchy.co/notepad/index.html to get better understanding of what it does and try to explain it in index.html

A sample description could be: This is an app where one can write anywhere on the screen.

This description can be displayed only to new users. localstorage can be used to identify new users.
