# Genkit JS
## Prerequisites
Ensure the `genkit` CLI is available.
- Run `genkit --version` to verify. Minimum CLI version needed: **1.29.0**
- If not found or if an older version (1.x < 1.29.0) is present, install/upgrade it: `npm install -g genkit-cli@^1.29.0`.
**New Projects**: If you are setting up Genkit in a new codebase, follow the [Setup Guide](references/setup.md).
## Hello World
```ts
import { z, genkit } from 'genkit';
