Each workspace is a real project split into steps. Mentat guides you through each one, you apply what you learn in a real environment, and at the end you take away a working artifact you created yourself.
Mentoring at every step: the concept, the why behind it, and a concrete challenge.
You apply what you learned by writing it yourself, try it out and watch it work live.
Close the last step and the artifact is yours: publishable, installable, usable.
