Nice 🎇 Some more ideas:

• Graphical Architecture Overview (Relationships between Expr, Environment, Fields, Model, Nodes)
• API integration example with CMake/C++
• C++ Model extension example?

Nice sparkler Some more ideas:

* Graphical Architecture Overview (Relationships between `Expr`, `Environment`, `Fields`, `Model`, `Nodes`)

* API integration example with CMake/C++

* C++ Model extension example?

Yes, will add some of those :+1:. Also tried compiling to web (with success) to have an interactive playground but I think this is too much for this PR.
