Provide a better description of what this project does

[Musikolo]

When I see the home page of this project, there is a "What is this?" question. However, I find the answer provided extremely insufficient. I wish there is a more descriptive answer that describes what truly this package is, what problem it tries to address and what features it provides. I guess this is a small ask that many users would really appreciate it.

Thank you and keep up with the good work!
