+# DeOldify Browser Integration
+
+This directory contains a browser-based implementation of DeOldify using ONNX Runtime Web. It allows you to run colorization models directly in your web browser without a backend server (after the model is downloaded).
+
+## ⚠️ Important: How to Run
+
+Due to browser security policies (CORS), **you cannot simply double-click the HTML files** to run them. You must serve them via a local HTTP server.
+
+### Quick Start (Windows/Linux/Mac)
+
+If you have Python installed (which is likely if you're using DeOldify), simply run:
+
+```bash
+# Run this command in your terminal within this directory
+python -m http.server 8000
+```
+
+Then open your browser and visit:
+*   [http://localhost:8000](http://localhost:8000)
+
+### Using the Helper Script (Windows)
+
+We've provided a PowerShell script to make this easy:
+
+1.  Right-click `serve.ps1` and select "Run with PowerShell"
+2.  Or run it from the terminal: `.\serve.ps1`
+
+## Available Models
+
+*   **Artistic Model**: High quality, vibrant colors. Larger download (~243 MB).
+*   **Quantized Model**: Faster, smaller download (~61 MB), slightly lower quality.
+
+## Troubleshooting
+
+**"Failed to fetch" or CORS Errors:**
+If you see an error about CORS or "Failed to fetch" in the status log, it means you are likely trying to open the file directly (`file:///...`). Please use the HTTP server method described above.
+
+**Memory Issues:**
+The artistic model requires a significant amount of RAM. If the tab crashes, try closing other tabs or using the Quantized model.
