I wonder if we do need to also add some instructions on how to remove the old cask references and move to the new ones. Is that something you could add as a callout?

[RadekCap]

:) I don't know where are old cask references stored. We even haven't decided what about upgrade. Do we need to cover it somewhere etc.

This PR is about an update to our documentation to the currently working solution.

It would be nice to find someone who has more experience with homebrew maybe.
