Flic support in Homey?

There is this project from another Dutchy but while I have:

  • downloaded GitHub desktop
  • managed to get the project in GitHub Desktop
  • the files ready to access on my computer
  • some programming experience (VB, C#, Delphi)

I am at a loss how I get this code into / working with my Homey.

Does someone know how to do this, I see Java and JSON, must I build some sort of web platform first?
