-Example of a contextual state machine implementation in C(++)
+Example of a contextual state machine (generator methods) implementation in basic C++, using mostly C constructs.
 
-Goal:
-	A PoC full C implementation of 'generator' functions in C using the rather janky `_Generic`.
-	Currently the implementation is in an extremely small subset of C++ using only a few templates to get around C's janky implementation of generics.
+See `src/test/main.cpp` for example.
