-Framework extraction is in progress. The repository now contains the
-`internal/domain` model, application-neutral `internal/defaults`, and
-`internal/filecatalog` helpers that form the implementation foundation. It also
-contains internal prompt-definition and profile repositories, the embedded
-built-in profile catalog, artifact loading, Go-template rendering, output
-validation, model generation, and orchestration. These internal packages are
-not a consumer API, and the root package does not yet provide a usable public
-framework API, so there is no installation or usage example at this time.
+The root `promptkit` package provides the supported public engine. Consumers
+can configure filesystem or in-memory prompt, profile, and schema sources,
+prepare requests without generation, run requests with the built-in
+OpenAI-compatible client, or inject their own model client and artifact reader.
+See the [Go package consumer guide](docs/consumers/pkg-promptkit.md) for the
+public workflow and contract.
