+This will visualize the output of the model. 
+
+You can also export the segmentation to a pyramidal TIFF like so:
+```python
+import fast
+
+pipeline = fast.Pipeline.fromDataHub('breast-epithelium-segmentation', {'file': '/path/to/your/WSI'})
+pipeline.parse(visualization=False)
+output = pipeline.getPipelineOutputData('segmentation')
+fast.TIFFImagePyramidExporter.create('segmentation.tiff')\
+	.connect(output)\
+	.run()
+```
