+# CURE: Co-Evolving LLM Coder and Unit Tester via Reinforcement Learning Datasets
 
+This repository contains datasets used in the CURE framework for co-evolving LLMs for code generation and unit testing. The data is formatted using Stdio input/output for consistency.
 
+## Data Format
+
+We use the Stdio input/output format. For example, for the task of calculating the sum of a list:
 
-We use Stdio input/output format here. For example, for the task to calculate the sum of a list, the input and output are in the following format:
 ```python
-input = "5\n1 2 3 4 5\n"
+input = "5
+1 2 3 4 5
+"
 output = "15"
 ```
-CodeContests and CodeForces are using this format, however, MBPP and part of LiveCodeBench are using functional input/output format, such like
-```python
-assert sum_function([1, 2, 3, 4, 5]) == 15
-```
-In this project, we have converted the the functional format to the Stdio format to achieve consistency.

+CodeContests and CodeForces use this format. MBPP and parts of LiveCodeBench use a functional format (e.g., `assert sum_function([1, 2, 3, 4, 5]) == 15`), which has been converted to Stdio for consistency in this project.

+## Downloading the Datasets
 
+Use the `download_dataset.py` script to download the datasets. For example, to download LiveBench:
+
+```bash
+cd data
+python download_dataset.py --dataset LiveBench
 ```
+
+Replace `LiveBench` with other dataset names as needed.  To download training data use  `CodeContests_train`.
