+# Configurations and tasks
+| **Configuration** | **Task**                  | **Description**               |
+|-------------------|---------------------------|-------------------------------|
+| iris              | Multiclass classification | Classify iris type.           |
+| setosa            | Binary classification     | Is this a iris-setosa?        |
+| versicolor        | Binary classification     | Is this a iris-versicolor?    |
+| virginica         | Binary classification     | Is this a iris-virginica?     |

+
+# Usage
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("mstz/iris", "iris")["train"]
