# `info.json` Reference {#info-json-reference}

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](data_driven_config) page.

You can create `info.json` files at every level under `qmk_firmware/keyboards/<keyboard_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 information common to all Clueboard products, such as `manufacturer` and `maintainer`, while `qmk_firmware/keyboards/clueboard/66/info.json` contains more specific information about Clueboard 66%.

## Layouts {#layouts}

The `layouts` portion of the dictionary contains several nested dictionaries. The outer layer consists of QMK layout names, for example `LAYOUT_60_ansi` or `LAYOUT_60_iso`.

Each key dictionary in a layout describes the physical properties of a key. If you are familiar with the Raw Data format for [Keyboard Layout Editor](https://keyboard-layout-editor.com), you will find many of the concepts the same. Key names and layout choices are reused wherever possible, but unlike KLE each key is stateless, inheriting no properties from the keys that came before it.

All key positions and rotations are specified in relation to the top-left corner of the keyboard, and the top-left corner of each key.

The ISO enter key is represented by a 1.25u×2uh key. Renderers which utilize info.json layout data (such as `qmk info -l` and the QMK Configurator) should display this key as expected.
