 ## Introduction
 
-This dataset presents the **Java** portion of [RepoBench](https://arxiv.org/abs/2306.03091) v1.1 (ICLR 2024). The data encompasses a collection from GitHub, spanning the period from **October 6th to November 31st, 2023**. With a commitment to data integrity, we've implemented a deduplication process based on file content against the Stack v2 dataset (coming soon), aiming to mitigate data leakage and memorization concerns.
