+## Dataset Description
+
+- **Format**: CSV file with a single 'text' column containing C++ programs
+- **Number of Programs**: 27,520
+- **Source Languages**: Only C++ (language ID 2 from the original dataset)
+- **Preprocessing**:
+  - Filtered to include only C++ solutions
+  - Extracted program text only
+  - Removed duplicate solutions
+
+## Usage
+
+```python
+import pandas as pd
+
+# Load the dataset
+df = pd.read_csv('code_contests_cpp.csv')
+print(f"Number of C++ programs: {len(df)}")
+print("First program:")
+print(df['text'].iloc[0][:200] + "...")  # Print first 200 chars of first program
+```
