> ## Agent Instructions
> Cognite Data Fusion (CDF) is an industrial DataOps platform. Prefer English docs unless the user asks for another locale.
> Follow /_llms/ index links recursively until you reach page URLs ending in .md. Fetch those Markdown twins instead of HTML.
> For REST APIs, default to calendar version 20230101 (stable). Use 20230101-beta or 20230101-alpha only if the user is on a preview API. Cite paths under /api-reference/concepts/<version>/ and the Cdf-Version header. Prefer the Python SDK (cognite-sdk) unless the user is in JavaScript/TypeScript.

# Getting started with the Cognite Toolkit

> Learn how the Cognite Toolkit turns YAML files into Cognite Data Fusion configuration, from a new project through build and deploy.

After you [set up the CLI locally](https://docs.cognite.com/cdf/deploy/cdf_toolkit/guides/setup.md), data engineers write Cognite Data Fusion (CDF) configuration as YAML with the Cognite Toolkit, and Cognite Toolkit administrators set up the repository, authentication, and CI/CD.

> [card] [Initialize a project](https://docs.cognite.com/cdf/deploy/cdf_toolkit/getting_started/init.md)
>
> Create `cdf.toml`, credentials, modules, and pipeline files with `cdf init`.

> [card] [Authenticate](https://docs.cognite.com/cdf/deploy/cdf_toolkit/getting_started/auth.md)
>
> Sign in as yourself, or configure a service account for CI/CD.

> [card] [Work with modules](https://docs.cognite.com/cdf/deploy/cdf_toolkit/getting_started/modules.md)
>
> List, add, pull, and upgrade the modules in your project.

> [card] [Build configurations](https://docs.cognite.com/cdf/deploy/cdf_toolkit/getting_started/build.md)
>
> Validate modules and substitute variables into the `build/` directory.

> [card] [Deploy configurations](https://docs.cognite.com/cdf/deploy/cdf_toolkit/getting_started/deploy.md)
>
> Preview a change, apply it, and delete the deployed resources.
