-Genkit CLI.
+# Firebase Genkit CLI
 
-Right now this is just scaffolding. To build,
+The package contains the CLI for Firebase Genkit, an open source framework with rich local tooling to help app developers build, test, deploy, and monitor AI-powered features for their apps with confidence. Genkit is built by Firebase, Google's app development platform that is trusted by millions of businesses around the world.
 
+Review the [documentation](https://firebase.google.com/docs/genkit) for details and samples.
+
+To install the CLI:
+
+```bash
+npm i -g genkit
 ```
-pnpm i
-pnpm build
-```
 
-After executing `npm link`, the `genkit` binary will be in your local path.
-Call `genkit example` to see the example.

-We're following a slightly different architecture from Firebase Tools. For
-commands, Firebase Tools relies on node `require()` calls to dynamically load
-code. This is discouraged (in fact, disabled per our TSLint) so instead
-all files (and thus all commands) need to be directly referenced from something
-in the tree of imports. See `src/cli.ts`.
