+The information contained in `info.json` is combined with the `config.h` and `rules.mk` files, dynamically generating the necessary configuration for your keyboard at compile time. It is also used by the [QMK API](https://github.com/qmk/qmk_api), and contains the information [QMK Configurator](https://config.qmk.fm/) needs to display a representation of your keyboard. Its key/value pairs are ruled by the [`data/schemas/keyboard.jsonschema`](https://github.com/qmk/qmk_firmware/blob/master/data/schemas/keyboard.jsonschema) file. To learn more about the why and how of the schema file see the [Data Driven Configuration](https://docs.qmk.fm/#/data_driven_config) page.
 
 You can create `info.json` files at every level under `qmk_firmware/keyboards/<name>`. These files are combined, with more specific files overriding keys in less specific files. This means you do not need to duplicate your metadata information. For example, `qmk_firmware/keyboards/clueboard/info.json` specifies `manufacturer` and `maintainer`, while `qmk_firmware/keyboards/clueboard/66/info.json` specifies more specific information about Clueboard 66%.

 ### Layout Format
 
 Within our `info.json` file the `layouts` portion of the dictionary contains several nested dictionaries. The outer layer consists of QMK layout macros, for example `LAYOUT_ansi` or `LAYOUT_iso`.
