Better README.md

[wojciechczerniak]

Description

Readme will be published to NPM, we should move technical details to documentation and rework the readme.md for an upcoming release. We can use the table of content from HoT:

• Logo
• Description and badges
• Screenshot? 🤔
• Installation
• Usage
• Features
• Documentation
• Support and contribution
• Browsers compatibility
• License
• Credits
