 ## 🚀 Usage
 
+You can use this model with the `diffusers` library as follows:
+
 ```python
 from diffusers import DDPMPipeline
+
+# Load the pipeline
 pipeline = DDPMPipeline.from_pretrained("jiayangshi/synchrotron_pixel_diffusion")
-)
 
-model.eval()
+# Access the UNet model
+model = pipeline.unet
+model.eval()
+```
