Currently 'Adonis/Middleware/Static', is documented only under middelware section of documentation. https://adonisjs.com/docs/4.1/middleware#_server_middleware

I think it should be also noted under file uploads or file storage sections.

It is really inconvenient and little bit illogical that you need to read through middleware section of documentation too if you want to receive files from public folder.
In middleware part of documentation it is only mentioned once in example, but there is nothing to explain this line / middleware

I can fill in PR if anyone has ideas where it should be documented. I'm not sure myself, if it should be somewhere under file uploads or file storage 🤔
