Create your first wireframe

Sign up, then press the + button in the header or New wireframe on the Projects page. A new wireframe opens with one Desktop frame.

Open Components in the left panel and click a component: it lands in the selected frame, under whatever is already there. You can also drag a component onto any frame.

Select anything to edit it in the right panel. Everything saves automatically, and the save state sits next to the name in the top bar.
