> ## Agent Instructions
> These docs cover learner integrations through Hosted Lab Pages, the SDK, and the REST API. Content management is outside this integration scope.
> Read the setup page for the chosen approach before implementing it. Keep organization API keys and hosted mint secrets on the server.
> The public SDK is coming soon. Check the SDK quickstart for current availability. Do not invent installation commands or direct readers to a private package.
> Cybr provides completion tracking and CTF verification. The integrating platform decides whether to award points.
