As I've said before, there's an opportunity waiting for somebody who is willing to put some effort into creating a good, lightweight, modern, developer-friendly guide to UML. 💰
Would love simple projects with UML/ArchiMate from you which can make learning path easier. I can see "Hello World" of UMLs and its derivatives, but not more. We have many tutorials of coding with latest tech but not much with also how to integrate standards with them.
