+# R<sup>2</sup>ec: Towards Large Recommender Models with Reasoning
+
+R<sup>2</sup>ec is a large recommender model with reasoning, generating both natural language rationales and ranked item predictions. 
+The model is fine-tuned with reinforcement learning to enhance its reasoning capabilities for more effective recommendations.
