Of course you can !
There no more recent toturial as the mod did not change, if you have any question, feel free to ask.
2 hints :
- If you want contractors to deliver full grown civilian, you will need a "Civilian Contractor Dock" and allow delivery (contextual menu of the part).
- If you want young baby kerbals to be born, you will need any civilian part, at least 2 kerbals (one female, one male) and allow them to breed (contextual menu of the part).
Enjoy !
