[docs] add docs for the PR

[mserico]

Improve the README.md based on the newly merged PR: #22
You should write high-quality human-like docs for a modern OSS software. Don't write in the GPT-flavor. Don't write too long, keep it tidy docs. Don't use itemized list to describe things like "Use Cases", "Best practice" or "what it can do"
Don't add too long text, keep it short and to the point
