-Easily detect Performance, Hydration, and Security issues in your Nuxt application !
+**A Nuxt module that provides real-time feedback on your application's performance, accessibility, and security right in your browser.**
 
-- [✨  Release Notes](/CHANGELOG.md)
+Nuxt Hints integrates directly into the Nuxt DevTools, giving you actionable insights to improve your web vitals, fix hydration mismatches, and audit third-party scripts without ever leaving your development environment.
+
+- [✨Release Notes](/CHANGELOG.md)
 
 ## Features
 
-### 🚀 **Performance Analysis**
-- **LCP (Largest Contentful Paint) Optimization**: Identifies images that could benefit from modern formats (WebP, AVIF), proper sizing, fetch priority, and preloading
-- **CLS (Cumulative Layout Shift) Detection**: Warns about layout shifts caused by images without dimensions
-- **Loading Performance**: Tracks and reports slow-loading elements (>2.5s)
-- **Image Best Practices**: Validates proper `width`, `height`, `loading`, and `fetchPriority` attributes
+- **🚀 Rich DevTools UI**: A dedicated tab in Nuxt DevTools to visualize issues, inspect elements, and get recommendations.
+- **💧 Hydration Mismatch Debugging**: Side-by-side diffing of server-rendered and client-hydrated HTML to pinpoint the exact cause of mismatches.
+- **⚡️ Web Vitals Analysis**: Real-time metrics for LCP, INP, and CLS with detailed attribution and element-specific optimization tips.
+- **📦 Third-Party Script Auditing**: Dashboard to monitor performance, identify render-blocking scripts, and get security recommendations.
+- **🔍 Interactive Diagnostics**:
+  - **Hover to Highlight**: Hover over an issue in the DevTools to highlight the corresponding element on your page.
+  - **Click to Inspect**: Click to open the component source file directly in your code editor.
+- **💡 Actionable Console Warnings**: Clear, concise console messages that guide you to best practices and performance improvements.
 
-### 📦 **Third-Party Script Monitoring**

+## Quick Setup
+
+1.  Add `@nuxt/hints` dependency to your project:
+    ```bash
+    # Using pnpm
+    pnpm add -D @nuxt/hints
 
-That's it! You can now use Nuxt Hints in your Nuxt app ✨
+    # Using yarn
+    yarn add --dev @nuxt/hints
+
+    # Using npm
+    npm install --save-dev @nuxt/hints
+    ```
+
+2.  Add `@nuxt/hints` to the `modules` section of `nuxt.config.ts`:
+    ```js
+    export default defineNuxtConfig({
+      modules: [
+        '@nuxt/hints'
+      ]
+    })
+    ```
+
+That's it! Open your Nuxt app, go to the DevTools, and click the Nuxt Hints icon to get started.
 
 ## How It Works
 
 ### Performance Monitoring
+Nuxt Hints uses `web-vitals` to gather Core Web Vitals metrics and automatically logs any metrics that need improvement. It listens for INP, LCP, and CLS and provides detailed attribution for each.
 
-Nuxt Hints uses the **Performance Observer API** to monitor your application.
+### Hydration Mismatch Detection
+The module hooks into Vue's hydration process to compare the server-rendered DOM with the client-side DOM. When a mismatch is detected, it captures the pre- and post-hydration HTML for inspection.
 
 ### Third-Party Script Analysis
-
-The module automatically detects and analyzes third-party scripts.
+Using a combination of a Nitro plugin and client-side observers, Nuxt Hints tracks every script loaded on the page, measuring its performance and analyzing its attributes.
 
 ### Example Console Output
-
-When Nuxt Hints detects issues, you'll see warnings in console like:
