Configuration

Forgather configurations are YAML files preprocessed by Jinja2, parsed with custom YAML tags, and materialized into Python objects through a node graph. This section is a reference for the configuration language and the system that runs it.

For the conceptual overview (what a project is, how the pipeline works), start with Core Concepts.
