+## Quick Start (Recommended) <UIcon name="i-heroicons-rocket-launch" />
+
+The fastest way to get started with TresJS is using our interactive CLI wizard:
+
+::code-group
+```bash [npm]
+npx create-tres my-tres-project
+```
+
+```bash [yarn]
+yarn create tres my-tres-project
+```
+
+```bash [pnpm]
+pnpm create tres my-tres-project
+```
+::
+
+The CLI provides an **interactive wizard** that guides you through:
+
+::prose-list
+- 🎯 **Template selection**: Choose between Vue + Vite or Nuxt
+- 📦 **Ecosystem packages**: Select from TresJS ecosystem packages (Cientos, Post-processing, Leches)
+- 🔧 **TypeScript support**: Type safe development with TypeScript
+- 📏 **ESLint integration**: Code quality with TresJS ESLint config
+::
+
+::prose-note
+This is the **recommended approach** for new projects as it handles all the configuration automatically and lets you choose exactly what you need.
