This User Guide is organized by what you are doing: understanding the core concepts, authoring a flow, running it, and extending DV Flow with your own tasks.

New to DV Flow Manager? Start with Introduction for the mental model (packages, tasks, and dataflow) and Quickstart to build your first flow. The chapters below then go deeper on each topic.

• Core Concepts – packages, tasks, and how dataflow ties them together.

• Authoring Flows – parameters, expressions, filters, visibility, error handling, and the standard library.

• Running Flows – incremental/up-to-date execution and task runners.

• Extending DV Flow – implementing your own tasks (shell first, then Python) and advanced features.
