-## Installation
+## Quick Start
+
+The fastest way to get started — install the marketplace and let the plugin recommender auto-detect what you need:
+
+```bash
+# 1. Add the marketplace
+/plugin marketplace add pleaseai/claude-code-plugins
+
+# 2. Install the plugin recommender
+/plugin install please-plugins@pleaseai
+
+# 3. Scan your project and install recommended plugins
+/please-plugins:setup
+```
+
+The `please-plugins` plugin automatically detects your project's dependencies (`package.json`, lock files, `turbo.json`, etc.) and recommends matching plugins. It also watches for new package installs (`bun add`, `npm install`, `pnpm add`) and suggests plugins on the fly.
+
+**Supported ecosystems:** Nuxt, Vue, Vite, Vitest, Pinia, VueUse, Prisma, Supabase, Firebase, Playwright, Sentry, Stripe, Mastra, AI SDK, Turborepo, pnpm, and more.
