+# DebugTraj-50K: Developer Debugging Trajectory Dataset
+
+50,000 debugging sessions with 665,364 step-by-step behavioral events across 8 programming languages and 71 error types.
+
+## Load in one line
+
+```python
+import pandas as pd
+sessions = pd.read_csv("hf://datasets/pyofpython/debugtraj-50k/code_debugging_sessions_fixed.csv")
+events   = pd.read_csv("hf://datasets/pyofpython/debugtraj-50k/code_debugging_events_fixed.csv")
+```
+
+## What makes this unique
+
+Most bug datasets only say "bug was fixed in 23 minutes."
+This dataset records every step taken during those 23 minutes — every compile, edit, search, test, and commit.
+
