README improvement

[tiomchik]

Is your feature request related to a problem? Please describe. The current README may seem unreadable to someone.

Describe the solution you'd like We can format it, for example, add emojis, remove unnecessary whitespace and adjust the structure.

Describe alternatives you've considered Add a README in other languages (this is more like an idea for future issues or/and pull requests).

Additional context It may be appropriate to use the Prettier extension for VS Code. I'll send a pull request as soon as possible to close this issue.
