+# Static2API Frontend
+
+This is a simple frontend that displays data from the Static2API application. It's designed to work with the API without requiring any changes to the container or backend.
+
+## Usage
+
+1. Start the Static2API application either directly or via container:
+   ```
+   python main.py
+   ```
+   or
+   ```
+   ./run_container.sh
+   ```
+
+2. Open the `index.html` file in your browser:
+   - You can use any static file server
+   - Or simply open the file directly in your browser
+
+3. The frontend will fetch data from the following endpoints:
+   - `/` - Root endpoint
+   - `/api/users` - Users data
+   - `/api/contacts` - Contacts data
+
+## CORS Support
+
+The FastAPI application has been updated with CORS middleware to allow cross-origin requests from this frontend. This means you can:
+
+1. Open the HTML file directly in your browser
+2. Access the API endpoints without CORS restrictions
+3. Serve the frontend from any static file server
+
+No additional configuration is needed for CORS support.
