# Configuration

LeRobot configuration is plain dataclasses parsed by [draccus](https://github.com/dlwh/draccus), so every
field is settable from the CLI. [`TrainPipelineConfig`] is the top-level object for `lerobot-train`.

Polymorphic configs (policies, robots, environments) use `draccus.ChoiceRegistry`: a subclass registers
itself with `@register_subclass("name")` and is then selectable by that name on the command line.
