Document usage without decorators

[kubk]

Readme file states that this library works without decorators:

Could you document how to use it without decorators? We are using Mobx 6 and decorators are turned off

Hi, inject utility isn't what you needed?

[kubk]

@kirilldronkin How can I use it with function components? The example only shows how to use it with class components.

[kirilldronkin]

useInstance hook is intended for usage in function components.

@kirilldronkin Thank you! I think this issue can be closed. Are you a maintainer of the project? Is it still alive?

Is there also a way to use registerIn without decorators?
