+
+The dataset contains 27 CTs with corresponding airways and lung annotations. The folder structure is described below.
+
+The easiest way to access the data is through Python with Hugging Face's [datasets](https://pypi.org/project/datasets/) package:
+```
+from datasets import load_dataset
+
+# downloads data from Zenodo through the Hugging Face hub
+# - might take several minutes (~5 minutes in CoLab)
+dataset = load_dataset("andreped/AeroPath")
+print(dataset)
+
+# list paths of all available patients and corresponding features (ct/airways/lungs)
+for d in dataset["test"]:
+  print(d)
+```
+
+A detailed interactive demo on how to load and work with the data can be seen on CoLab: <a href="https://colab.research.google.com/gist/andreped/6070d1d2914a9ce5847d4b3e687188b7/aeropath-load-dataset-example.ipynb" target="_parent"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"/></a>
