+::note
+Nuxt Content infers collection types from the schema you provide, so the `ogImage` field needs the same [Zod](https://zod.dev) instance your project uses. The module resolves Zod from your project (it's an optional peer dependency), so this works automatically. If you have multiple Zod versions installed and `ogImage` is missing from the generated `ContentCollectionItem` type, pass your instance explicitly with `defineOgImageSchema({ z })`{lang="ts"}.
+::
+
 To ensure the tags gets rendered you need to ensure you're using the `defineOgImage()`{lang="ts"} composable with the `ogImage` key.
