Missing README.md file

Thanks, looks great!

It's true that the README.md guidelines used to say "Two lines prior to headings (except the first one)"

https://www.drupal.org/docs/develop/managing-a-drupalorg-theme-module-or...

But the intention is, that at the very top it should be like this, with only a single line after the project name:

# Notifybar

## Table of contents

- Introduction
[...]

I have updated the guidelines to "Two lines prior to ## headings, but only one line after project name" to try to make it clearer what the intended formatting is.

Also, perhaps you can create an issue fork (click "Create issue fork") and commit to that, for easier preview and commenting?

Thanks @Dheeraj Jhamtani, looking good. I added a few comments.
