# Definition {#cb-definition}

The minimal viable definition consists of a folder with a YAML file named
**config.yaml** inside. All other resources are split into three folders
named **assets**, **templates** and **language**.

-   `my-content-block`
    -   `assets`([details](https://docs.typo3.org/permalink/friendsoftypo3/content-blocks:cb-definition-assets@main))
