I was trying to give options to users here, but honestly I don't really know what to suggest...

Ideally, the examples we had below would work post deploy (the one from circleci seems to work for example), but that doesn't seem the case. @lventura-codacy @afsmeira @lorandszakacs could any of your gentle souls take a look at these examples and review / improve them? 😭 thank u guys
