-# ArkTS-CodeSearch: A Open-Source ArkTS Dataset for Code Retrieval
+# Recommended Version: ArkTS-CodeSearch-Pro
 
-> **Looking for the improved version?** Please use [ArkTS-CodeSearch-Pro](https://huggingface.co/datasets/hreyulog/arkts-code-docstring-pro). The Pro dataset applies stricter open-source license filtering, keeps only repositories with `stars > 0`, normalizes comments, removes license/copyright headers and code-only docstrings, enforces minimum docstring length, and performs global code/query deduplication. This original dataset is retained for compatibility.
+**We strongly recommend using [ArkTS-CodeSearch-Pro](https://huggingface.co/datasets/hreyulog/arkts-code-docstring-pro) for all new research and development.**  
+The Pro version is the actively maintained release and provides improved data quality through stricter open-source license filtering, repository quality control (`stars > 0`), comment normalization, removal of license/copyright headers and code-only comments, minimum docstring length filtering, and global code/query deduplication.
+
+The original [ArkTS-CodeSearch](https://huggingface.co/datasets/hreyulog/arkts-code-docstring) dataset is preserved only for backward compatibility and reproducing results from previous versions. **New experiments should use ArkTS-CodeSearch-Pro instead.**
