+### Google Genkit: Full-Stack AI Framework
+
+[Genkit](https://genkit.dev/) is Google's open-source framework for building production-grade AI-powered applications and agents across **JavaScript/TypeScript**, **Go**, **Dart**, and **Python**. Genkit provides first-class A2UI support through dedicated server middleware and client helpers in its JavaScript/TypeScript (`@genkit-ai/a2ui`), Go (`github.com/firebase/genkit/go/plugins/a2ui/exp`), and Dart (`genkit_a2ui`) SDKs.
+
+**How Genkit uses A2UI:**
+
+Genkit's A2UI middleware turns standard AI agents into interactive UI generators without manual prompt engineering or brittle JSON parsing. Because emitted envelopes are byte-compatible across all Genkit SDKs, an agent written in TypeScript, Go, or Dart can stream interactive UI surfaces to web renderers (`@a2ui/lit`, `@a2ui/react`, `@a2ui/angular`) or Flutter (`genui`).
+
+- **Multi-language middleware**: Enable A2UI on any agent or prompt in TypeScript (`a2ui()`), Go (`&a2uix.Surfaces{}`), or Dart (`a2ui()`).
+- **Automatic catalog injection & validation**: Automatically injects your approved component definitions into system instructions and validates every streamed envelope against your catalog schema.
+- **Two-way interactive loop**: Client helpers (`a2uiEnvelopesFromParts` and `actionToMessage`) make it seamless to stream live UI updates and route user interactions back to the agent as the next conversation turn.
+- **Full observability**: Inspect every prompt, tool call, and streamed A2UI envelope in the local Genkit Developer UI (`genkit start`).
+
+**Try it:**
