+# CIFAR-10 Diffusion Model
+
+🎨 **A diffusion model trained from scratch on CIFAR-10 dataset**
+
+## Model Details
+- **Architecture**: SimpleUNet with 16.8M parameters
+- **Dataset**: CIFAR-10 (50,000 training images)
+- **Training Time**: 14.54 minutes on RTX 3060
+- **Final Loss**: 0.0363
+- **Image Size**: 32x32 RGB
+- **Framework**: PyTorch
+
+## Quick Start
+
+```python
+import torch
+from model import SimpleUNet, DDPMScheduler, generate_images
+
+# Load the trained model
+checkpoint = torch.load('complete_diffusion_model.pth')
+model = SimpleUNet(**checkpoint['model_config'])
+model.load_state_dict(checkpoint['model_state_dict'])
+model.eval()
+
+# Initialize scheduler
+scheduler = DDPMScheduler(**checkpoint['diffusion_config'])
+
+# Generate images
+generated_images = generate_images(model, scheduler, num_images=8)
+```
+
+## Installation
+
+```bash
+pip install torch>=2.0.0 torchvision>=0.15.0 matplotlib tqdm pillow numpy
+```
+
+## Files Included
+- `complete_diffusion_model.pth` - Complete model with config (64MB)
+- `model_info.json` - Training details and metadata
+- `diffusion_model_final.pth` - Final training checkpoint (64MB)
+- `inference_example.py` - Ready-to-use inference script
+
+## Training Details
+- **Epochs**: 20
+- **Batch Size**: 128
+- **Learning Rate**: 1e-4 (CosineAnnealingLR)
+- **Optimizer**: AdamW
+- **GPU**: NVIDIA RTX 3060 (0.43GB VRAM used)
+- **Loss Reduction**: 73% (from 0.1349 to 0.0363)
+
+## Hardware Requirements
+- **Minimum**: 1GB VRAM for inference
+- **Recommended**: 2GB+ VRAM for training extensions
+- **CPU**: Works but slower
+
+## Results
+The model generates colorful abstract patterns that capture CIFAR-10's color distributions. 
+With more training epochs (50-100), it should produce more recognizable objects.
+
+## Improvements
+To get better results:
+1. **Train longer**: 50-100 epochs instead of 20
+2. **Larger model**: Increase channels/layers
+3. **Advanced sampling**: DDIM, DPM-Solver
+4. **Better datasets**: CelebA, ImageNet
+5. **Learning rate**: Experiment with schedules
+
+## Model Architecture
+- **U-Net based** with ResNet blocks
+- **Time embedding** for diffusion timesteps
+- **Attention layers** at multiple resolutions
+- **Skip connections** for better gradient flow
