+## Introduction
+This repository hosts the official code and data artifact for the paper [NextCoder: Robust Learning of Diverse Code Edits
+](https://arxiv.org/abs/2503.03656)
+
+The work is the development of code-editing LLMs, synthetic data generation pipeline and a novel finetuning methodology.
+
+## Repository Structure
+- [data](data/): contains the scripts and files required to generate synthetic dataset for code-editing as per the pipeline proposed in the paper
+- [train](src/train/) contains the scripts and files for finetuning with SeleKT, LoRA and usual SFT.
 
 ## Model Usage
 ```python
