}

That's the whole setup. The engine inlines the official PostHog loader — no extra dependency, no script configuration — and tracks pageviews natively, including client-side navigations between docs pages.

Field	Required	Notes
`apiKey`	Yes	Your publishable project key (`phc_...`) — safe to commit
`apiHost`	—	Defaults to PostHog US cloud; set `https://eu.i.posthog.com` for EU residency or your reverse-proxy origin

Publishable keys are designed to be public — they can only ingest events. Keep personal or server API keys out of docs.json all the same.
