-## USACO 2025 Open Contest Dataset
-
-### Dataset Description
-The USA Computing Olympiad (USACO) is a prestigious algorithmic programming competition for high school students in the United States, consisting of four difficulty levels: Bronze, Silver, Gold, and Platinum. Each level contains a set of challenging problems that test algorithmic thinking and implementation skills, making USACO a valuable benchmark for evaluating the reasoning and problem-solving capabilities of large language models. This dataset contains problems and test cases from the USACO 2025 Open Contest.

+# rStar-Coder: A Large-Scale Verified Dataset for Code Reasoning
+
+This dataset, introduced in the paper [rStar-Coder: Scaling Competitive Code Reasoning with a Large-Scale Verified Dataset](https://huggingface.co/papers/2505.21297), significantly advances code reasoning in large language models (LLMs).  rStar-Coder contains 418K competition-level code problems, 580K long-reasoning solutions, and rich test cases of varying difficulty.  This dataset was constructed through a three-step process: curating competitive programming problems, creating a reliable input-output test case synthesis pipeline, and augmenting problems with high-quality, test-case-verified long-reasoning solutions.
+
+The rStar-Coder dataset enables significant improvements in LLM code reasoning capabilities.  Experiments on Qwen models demonstrate superior performance compared to models trained on other datasets, achieving leading results even with smaller model sizes.
+
+**Key Features:**
+
+* 418K competition-level code problems
+* 580K long-reasoning solutions
+* Rich test cases of varying difficulty
+* Verified input-output test cases
+
+**Dataset Usage:**
+
+The dataset can be used to train and evaluate LLMs for code reasoning tasks.  The detailed structure and usage instructions are available in the GitHub repository.
