i understand the idea of this file but im not sure how we should could keep it up to date. There are things mentioned like PHP class and mehod names which are purely an implementation detail and can change anytime. These details are imo not relevant to the user. And also not understood without further context.

I would rather recommend adding a shared interface and adding documentation there or something maybe via php attribute

[Sebobo]

People rarely look at the code for documentation.

I want a doc page for each feature and explain their use cases. So this is the (auto-generated) start of that. It will require screenshots etc. to give more value.

interesting idea ... but isnt it already limited because the composer script only looks up phpstan which must be in $PATH and its only in path if this package itself is the root which it never actually is if it should work in production with Flow?

"require-dev": {
        "phpstan/phpstan": "^1.10"

[Sebobo]

Huh? Composer finds all binaries from all dependencies if they marked them. This path workaround is just so that phpstan finds all relevant classes no matter where and how the package is installed with the same config.
