info.json Reference :id=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, and contains the information QMK Configurator needs to display a representation of your keyboard. Its key/value pairs are ruled by the data/schemas/keyboard.jsonschema file. To learn more about the why and how of the schema file see the Data Driven Configuration 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 :id=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, 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.
