Rendering Flows with Visualforce

Visual Workflow allows administrators to build applications, known as flows, that guide users through screens for collecting and updating data. For example, you can use Visual Workflow to script calls for a customer support center or to generate real-time quotes for a sales organization.

The standard user interface for running a flow can't be customized. Visualforce is the core technology that gives developers a more powerful way of building applications and customizing the look and feel of applications. Visual Workflow can leverage this technology to customize the user interface when running flows.
