SilverBullet's configuration can be tweaked using the `config.set` Space Lua API. This page defines all built-in configurations available. Individual Plugs and Space Lua scripts may define their own.

# Built-in options (schema)

This defines the [JSON schema](https://json-schema.org/) for built-in configuration.
