+# PyEdu Dataset Integration Configuration
+
+This directory contains configuration files for integrating the pyedu dataset into OpenSeek training pipelines.
+
+## About PyEdu Dataset
+
+PyEdu is a high-quality educational Python code dataset that is a subset of the "stack-edu" subset from smollm-corpus. Key characteristics:
+
+- **Source**: https://huggingface.co/datasets/Leon-Leee/unofficial-pyedu
+- **Size**: ~6GB
+- **Quality**: High-quality according to the smollm-v2 tech report
+- **Content**: Educational Python code examples
+- **Use Cases**: Further training, annealing, or synthesizing datasets
+
+## Configuration Files
+
+- `config_pyedu_integration.yaml`: Experiment-level configuration for pyedu integration
+- `train/train_pyedu_integration.yaml`: Task-level configuration with pyedu dataset included
+
+## Usage
+
+To use these configurations:
+
+1. Ensure the pyedu dataset is downloaded and preprocessed
+2. Update the `dataset_base_dir` in the config file to point to your data directory
+3. Adjust the data mixture ratios as needed for your specific training requirements
+4. Run training with the provided configuration files
+
+## Data Mixture Strategy
+
+The pyedu dataset can be integrated into existing training pipelines in several ways:
+
+1. **Annealing**: Use pyedu for final training phases to improve code understanding
+2. **Synthesis**: Use pyedu as source material for generating additional training data
+3. **Mixed Training**: Include pyedu as part of the regular training data mixture
+
+The configuration provided uses a balanced approach, incorporating pyedu alongside existing code datasets.
