# Groundrun docs

> Reference documentation for the groundrun command-line tool, the rig and scenario YAML format, and how the Groundrun system fits together. Written for an agent or engineer driving the product.

## Pages

- [Docs index and system overview](https://groundrun.io/docs.md): how the rig, the coordinator, and the flow builder connect.
- [CLI cheat sheet](https://groundrun.io/docs/cli-cheat-sheet.md): every `groundrun` command, with its flags and an example.
- [YAML format cheat sheet](https://groundrun.io/docs/yaml-format-cheat-sheet.md): the rig and scenario YAML file formats, every actor and step type, and every pass criterion.

Each page above is also available as a human-readable HTML page: the docs index and system overview at `https://groundrun.io/docs/`, and the other two at the same path with no `.md` extension, for example `https://groundrun.io/docs/cli-cheat-sheet/`.
