# Concepts

> Learn how pipelines are described in JSON and how tasks, artifacts, and parameters work together.

Pipelines are described in a JSON format and consist of a set of tasks.

``` json
{
    "tasks": [
        {
            "description": "Extract design",
            "type": "extract-project-design",
            "parameters": { ... },
            "outputArtifacts": [ ... ]
        },
        {
            "description": "Render design",
            "type": "render-hires",
            "inputArtifacts": [ ... ],
            "parameters": { ... },
            "outputArtifacts": [ ... ]
        },
        {
            "description": "Finalize",
            "type": "finalize",
            "finalArtifacts": [ ... ]
        }
    ]
}
```

The tasks can consume and produce artifacts and work depending on some parameters, which can be configuration settings and project data.
