+# 📦 Screen2AX-Tree
+
+Screen2AX-Tree is part of the **Screen2AX** dataset suite, a research-driven collection for advancing accessibility in macOS applications using computer vision and deep learning.
+
+This dataset provides **hierarchical accessibility annotations** of macOS application screenshots, structured as serialized trees. It is designed for training models that reconstruct accessibility hierarchies from visual input.
+
+---
+
+## 🧠 Dataset Summary
+
+Each sample in the dataset consists of:
+- An application **screenshot** (`image`)
+- A serialized **accessibility tree** (`accessibility`): A JSON-formatted string representing the UI structure, including roles, bounds, and child relationships.
+
+**Task Category:**
+- `object-detection` (structured / hierarchical)
+
+**Language:**
+- English (`en`)
+
+---
+
+## 📚 Usage
+
+### Load with `datasets` library
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("MacPaw/Screen2AX-Tree")
+```
+
+### Example structure
+
+```python
+sample = dataset["train"][0]
+print(sample.keys())
+# dict_keys(['image', 'accessibility'])
+
+print(sample["accessibility"])
+# '{ "role": "AXWindow", "children": [ ... ] }'
+```
+
+You can parse the accessibility field as JSON to work with the structured hierarchy:
+
+```python
+import json
+
+tree = json.loads(sample["accessibility"])
+```
