+## Usage
+
+```python
+import json
+
+# Load tasks
+tasks = []
+with open("data/tasks.jsonl") as f:
+    for line in f:
+        tasks.append(json.loads(line))
+
+# Each task has: task_id, title, dimension, max_score, prompt_template
+print(tasks[0]["prompt_template"])
+```
+
+## Evaluation
+
+```bash
+pip install -e .
+python -m src.evaluate_v2 --task T01 --response "your model output" --breakdown
