I've tried to get `act` to work several times over the past few months, and never managed to get even a basic workflow to run locally. It kept giving cryptic errors that I had to dig into their code to figure out (e.g. requiring a GitHub Personal Access Token despite not mentioning it in the docs). It gave me the impression that it was far from functional, for now.

I eventually gave up and have been running Actions on GitHub from a branch, merging into the main one once it works.
