Please provide a tutorial

Hey,

Incremento seems impressive but obviously very complicated for a new user. It would be pretty useful to have a quick tutorial (or even better, a video showing a real incremento working session).

No file, test, or entry point is named. First clarify whether the project wants a written quick tutorial, a video, or both, then identify a representative Incremento working session to document. Done means a newcomer-facing tutorial or video that explains a real workflow clearly.
