Documentation

README

Excerpt

HTML Prototype

Build a credible model of a product decision. Match the artifact to the user's context instead of applying a recurring house style. The goal is not to make every possible screen. The goal is to make the important visual or behavioral question testable.

Choose the fidelity mode

Use one of two modes:

Mockup: Create a polished, responsive, mostly static artifact when the open question is visual hierarchy, layout, typography, color, or product fit.
Prototype: Create a working flow when the open question is navigation, input, state change, feedback, recovery, or transition.

This is the opening of the README. Read the full README on GitHub.
