The Vanilla OS SDK is a collection of libraries and tools that allow developers to create applications for the Vanilla OS platform in a standardized and consistent manner.
The SDK is currently in early development, its features are not yet stable and are subject to change. Also note that this SDK targets Vanilla OS Vision, not Orchid (Vanilla OS 2), so do not expect it to work in Orchid or any other operating system.
If you want to contribute to the SDK, check out the Contributing document.
