+# Dataset card for "MuGeminorum/HEp2"
+The HEp-2 (Human Epithelial type 2) dataset is a widely used benchmark in the field of medical image analysis, especially for the task of antinuclear antibody (ANA) pattern classification. The dataset contains microscopic images of HEp-2 cells stained with fluorescence, demonstrating multiple patterns of autoantibody binding associated with various autoimmune diseases. The HEp-2 dataset is utilized by researchers and practitioners to develop and evaluate algorithms for automated ANA pattern recognition to aid in the diagnosis of autoimmune diseases. The intricate patterns in this dataset test the robustness of computational models, making it a valuable resource for advancing the understanding of autoimmune diseases and the development of advanced medical image analysis techniques.
+
+## Usage
+```python
+from datasets import load_dataset
+
+data = load_dataset("MuGeminorum/HEp2")
+trainset = data["train"]
+validset = data["validation"]
+testset = data["test"]
+labels = testset.features["label"].names
+
+for item in trainset:
+    print("image: ", item["image"])
+    print("label name: " + labels[item["label"]])
+
+for item in validset:
+    print("image: ", item["image"])
+    print("label name: " + labels[item["label"]])
+
+for item in testset:
+    print("image: ", item["image"])
+    print("label name: " + labels[item["label"]])
+```
+
+## Maintenance
