Tutorials

These tutorials are hands-on lessons. Work through them at the keyboard, in order — each one builds on the last, and every step is meant to succeed exactly as written. They teach by doing; the reasoning behind what you are doing lives in the Explanation pages, and task-focused recipes live in the How-to Guides.

1. First Steps — define a couple of configuration objects, register them, and see how the registry links them together. The shortest path to the core idea.
2. Configuring Models — build up strongly typed, hierarchical configuration with pydantic models, register them, and wire dependencies between them.
3. Defining Workflows — turn configuration into runnable steps with contexts, results, and callable models, and meet the evaluators that run them.
4. Building an ETL Pipeline — assemble extract, transform, and load steps into an end-to-end pipeline driven by a single Hydra config.
5. Composing an ETL Application — grow that pipeline into a reusable, config-group-driven application with command-line dispatch.
6. Building a Configurable Calculator — the capstone: combine the functional @Flow.model API with config groups and CLI dispatch to build a fully configurable program from the command line.
