# PlantUML examples

PlantUML draws more diagram types than anything else here, and the syntax has been stable long enough to be worth learning properly.

These examples cover the types people actually use, plus a few that are worth knowing exist.

## Every example here is real

Each page holds a diagram that is stored, rendered and editable exactly like one you drew yourself. Open any of them, change something, and see what happens. Nothing here is a screenshot.
