# Why is it called “Flow”?

The user “flows” through multiple **screens** (steps) in order - Screen 1 → Screen 2 → … → last screen (Done). The structure (screens + components + navigation) is defined in a **Flow JSON** file that Meta validates and hosts. **SMSGatewayCenter** generates this JSON for you from the builder.
