Figma is the tool the industry has standardized on, and fluency is table stakes. The leverage is not in knowing every menu but in a few deep skills: auto layout, components and variants, variables, prototyping, and shared libraries. Learn those and the rest is lookup.
Figma’s official documentation and guided learning material for the editor.
Because Figma ships changes constantly, the official docs are the only source guaranteed to be current, which matters more here than production polish. Use it as lookup while you build a real screen rather than reading it end to end. Learn auto layout, components, and variables deeply here and treat the rest as reference.
