+# GitCode Code Dataset
+
+## Dataset Description
+
+This dataset was compiled from code repositories hosted on [GitCode](https://gitcode.com), a code hosting platform in China backed by CSDN (China Software Developer Network). GitCode serves as a domestic alternative to GitHub, widely used by Chinese developers, students, and enterprises for hosting open-source projects and educational resources, making this dataset particularly valuable for training code models with Chinese language understanding and Chinese coding conventions.
+

+
+## Dataset Creation
+
+### Pipeline Overview
+
+The dataset was created through a multi-stage pipeline:
+
+1. **User Discovery**: Collecting usernames via GitCode API
+2. **Repository Discovery**: Fetching repository lists for each user via GitCode API
+3. **Repository Cloning**: Using Git partial clone with blob size filtering
+4. **Content Extraction**: Extracting and filtering source code files
+5. **Parquet Generation**: Writing filtered records to Parquet shards with Zstd compression
+
+### Language Detection
+
+Programming languages are detected using [go-enry](https://github.com/go-enry/go-enry), a Go port of GitHub's Linguist library. Only files classified as **Programming** or **Markup** language types are included (Data and Prose types are excluded).
+
+### License Detection
+
+Licenses are detected by:
+1. Scanning for license files (`LICENSE`, `LICENSE.txt`, `LICENSE.md`, `COPYING`, etc.)
+2. Matching license text against known patterns (MIT, Apache 2.0, GPL variants, BSD, Creative Commons, etc.)
+3. Defaulting to "unknown" if no license can be detected
+
+**Blocked Licenses**: The following restrictive licenses are excluded from the dataset:
+- `cc-by-nd`, `cc-by-nd-2.0`, `cc-by-nd-3.0`, `cc-by-nd-4.0` (Creative Commons No-Derivatives)
+- `commons-clause`
+- `sspl`, `sspl-1.0` (Server Side Public License)
+
+### File Filtering
+
+Extensive filtering is applied to ensure data quality:
+

+
+#### Content Filtering
+- **UTF-8 Validation**: Files must be valid UTF-8 encoded text
+- **Binary Detection**: Files detected as binary by go-enry are excluded
+- **Generated Files**: Files with generation markers in the first 500 bytes are excluded:
+  - `generated by`, `do not edit`, `auto-generated`, `autogenerated`, `automatically generated`, `@generated`, `<auto-generated`, `this file is generated`
+- **Empty Files**: Files that are empty or contain only whitespace are excluded
+- **Long Lines**: Files with any line exceeding 1,000 characters are excluded
+- **go-enry Filters**: Additional filtering using go-enry's `IsVendor()`, `IsImage()`, `IsDotFile()`, and `IsGenerated()` functions
+- **Documentation-only Repos**: Repositories containing only documentation files (no actual code) are skipped
+
+### Source Data
+
+All data originates from public repositories hosted on [GitCode](https://gitcode.com).
+
+## Considerations for Using the Data
+
+### Personal and Sensitive Information
+
+The dataset may contain:
+- Email addresses in code comments or configuration files
+- API keys or credentials that were accidentally committed
+- Personal information in comments or documentation
+
+Users should exercise caution and implement appropriate filtering when using this data.
+
+### Licensing Information
+
+This dataset is a collection of source code from repositories with various licenses. Any use of all or part of the code gathered in this dataset must abide by the terms of the original licenses, including attribution clauses when relevant. The license field in each data point indicates the license of the source repository.
