+# Bundle Analyzer
+
+A Next.js application for visualizing bundle sizes and analyzing dependencies using interactive treemaps.
+
+This package is not published to npm. Instead it's built and vendored into the main `next` package during its build process.
+
+
+## Features
+
+- 📊 **Interactive Treemap**: Visualize bundle sizes with an interactive treemap interface
+- 🎯 **Route-based Analysis**: Analyze bundle data for specific routes in your application
+- 🔍 **Dependency Tracking**: View import chains and dependency relationships
+- 🎨 **Filter Controls**: Filter by environment (client/server) and file types (JS/CSS/JSON/Assets)
+- 🔎 **Search Functionality**: Search through files in your bundle
+
+## Updating
+
+When landing non-trivial changes, consider updating the demo site:
+* Site: https://turbopack-bundle-analyzer-demo.vercel.sh/
+* Repo: https://github.com/vercel/turbopack-bundle-analyzer-demo

+## Next.js Documentation (WIP)
+
+This app will be the new home for the Next.js documentation, currently in active development.
+
+### What to Expect
+
+- Content is being migrated from our internal monorepo
+- The design is not yet final
+- Internal tooling and structure may change
+
+### Contributing
+
+We'll open this app to contributions once the initial migration is complete. In the meantime, feel free to follow along or open an issue with the `documentation` tag.
+
+### Feedback
+
+For questions or early feedback, contact [Delba](https://github.com/delbaoliveira) or [Joseph](https://github.com/icyJoseph).
