+- **Customizable parameters**: width, height, steps, CFG scale, and seed
+- **Pre-cached examples** for instant preview and testing
+- **Professional UI** with Gradio interface
+
+## Example Prompts
+
+The app includes 11 pre-configured example prompts with optimized parameters:
+

+1. **Manual input**: Enter your own prompt and adjust parameters
+2. **Use examples**: Click on any example to load it instantly
+3. **Customize**: Modify example prompts to create variations
+4. **Generate**: Click the Generate button to create new images
+
+## Parameters
+
+- **Prompt**: Describe what you want to generate
+- **Negative Prompt**: Describe what you want to avoid
+- **Width/Height**: Image dimensions (512-2048px)
+- **Steps**: Number of denoising steps (1-50)
+- **CFG Scale**: How closely to follow the prompt (1-20)
+- **Seed**: Random seed for reproducible results (-1 for random)
+
+## Technical Details
+
+- Built with **Gradio** for the web interface
+- Uses **ComfyUI** workflow backend
+- Powered by **Chroma** diffusion model
+- Supports **GPU acceleration** with Spaces
+- **Automatic caching** for optimal performance
+
+## Running Locally
