+## What is Kangas DataGrid?
+
+Kangas DataGrid is a Python library for creating a table of text, numbers,
+and images, and then exploring them via a web browser-based UI.
+
+### A short example
+
+```python
+from kangas import DataGrid, Image
+
+dg = DataGrid(
+    name="Short Example",
+    columns=["Category", "Image", "Output"],
+)
+
+
+model = build_model()
+model.fit(x_train, y_train)
+outputs = model.predict(x_test)
+
+for index in range(len(x_test)):
+    dg.append([
+        y_test[index],
+        Image(x_test[index]),
+        outputs[index].argmax(),
+    ])
+
+dg.show()
+```
