# Flow Overview
Flows are interactive online multi-step forms (like 'wizards') which allow you to provide self-service facilities and capture data from external users.
# Anatomy of a flow
A flow represents the form as a whole, and will have a name and visibility setings (whether or not it's publicly accessible), and optionally parameters.
Within a flow, there'll be at least one stage, and within each stage there'll be at least one step and action.
Stages represent parts of the form that must be completed as a whole in order to proceed on to the next.
Steps are parts of the stage which get divided up for the sake of user friendliness.
Actions are what the stage goes on to do with the data it's collected.
Parameters (optional) are bits of information that might be needed in order to start a flow, and change how it acts.
