 # PairCoder
 A Pair Programming Framework for Code Generation via Multi-Plan Exploration and Feedback-Driven Refinement 
 
+## Overview
+In this paper, we draw on pair programming practices to propose **PairCoder**, a novel LLM-based framework for code generation. PairCoder incorporates two collaborative LLM agents, namely a *Navigator* agent for high-level planning and a *Driver* agent for specific implementation. 
+
+The *Navigator* is responsible for proposing promising solution plans, selecting the current optimal plan, and directing the next iteration round based on execution feedback. 
+The *Driver* follows the guidance of *Navigator* to undertake initial code generation, code testing, and refinement. This interleaved and iterative workflow involves multi-plan exploration and feedback-based refinement, which mimics the collaboration of pair programmers.
