How do I create a command line prompt?

I'm trying to create a command line prompt where people type in a string (like 'look' or 'north' or what have you) and the story moves to another scene based off of what they type. I'm new to Twine, but saw that some stories have this feature.
The project I'm working on starts with them entering a password to begin. I can't seem to find any information on what build to use (Harlowe, sugarcube, etc) to achieve this. How would I do this?
Thank you!
