New maintainer

[eval-on-point]

The README notes:

NOTE: this project is in maintencance mode, and looking for a new maintainer.

What is maintenance mode? What are the criteria for choosing a new maintainer? I may be happy to maintain the project, but know neither what qualifies someone to maintain the library nor what maintenance mode entails.

I'm also interested in contributing. For example: I struggled at first how to use middlewares and can help in documenting it and give a first-use code in README.md
