+
+## Usage Instructions:
+
+1. **Setup**: Make sure to clone the SAM-3D-objects repository and install dependencies
+2. **Image Upload**: Upload the image you want to convert to 3D
+3. **Mask (Optional)**: Upload a mask for better segmentation results
+4. **Configure**: Adjust the random seed if needed
+5. **Generate**: Click the generate button to create your 3D model
+6. **Download**: Save the generated PLY file when complete
+
+The app includes a "Built with anycoder" link as requested and provides a complete working interface for image-to-3D conversion using the SAM-3D-objects inference pipeline.
+
+**Important**: Before running, make sure to:
+1. Clone the repository: `git clone https://github.com/facebookresearch/sam-3d-objects`
+2. Install dependencies as per the repository requirements
+3. Ensure the model checkpoints are available in the `checkpoints/` directory
