Where is the code for the guides

[ByronMayne]

Hey there,
I have been trying to follow the Elsa guides and been having less then an ideal time. Most of the guides currently don't compile or have runtime exceptions. So I figured I would try to fix them out to contribute back. However the very first guide https://v2.elsaworkflows.io/docs/quickstarts/hello-world-console does not compile and blows up at runtime. Looking in the whole org I found the places where the is referenced, but they are archived projects. Where can this code be fixed it?

It's a really going to turn people away if the very first sample is very broken.
