 ## Dataset Structure
 
 ### Data Fields
 
-This dataset includes the following fields:
+| Field | Type | Description |
+|-------|------|-------------|
+| `code` | string | Content of the source file (UTF-8 encoded) |
+| `repo_name` | string | Name of the GitGud repository (format: `username/repo`) |
+| `path` | string | Path of the file within the repository (relative to repo root) |
+| `language` | string | Programming language detected by file extension mapping |
+| `license` | string | License of the repository (SPDX identifier or "unknown") |
+| `size` | int64 | Size of the source file in bytes |
 
-- `code`: Content of the source file (string)
-- `repo_name`: Name of the gitgud.io repository (string)
-- `path`: Path of file within the repository (string)
-- `language`: Programming language as inferred by file extension (string)
-- `license`: License of the repository, if available (string)
-- `size`: Size of source file in bytes (integer)
+### Data Format
+
+- **Format**: Apache Parquet with Zstd compression (level 19)
+- **File Structure**: 17 files (`gitgud-00000.parquet` to `gitgud-00016.parquet`)
+- **Rows per shard**: ~1,000,000 (except last shard: 322,315)

+    'language': 'C#',
+    'license': 'mit',
+    'size': 2048
+}
+```
+
+## Dataset Creation
+
+### Pipeline Overview
+
+The dataset was created through a multi-stage pipeline:
+
+1. **Repository Discovery**: Scraping public repository URLs from GitGud.io's GitLab API v4 endpoint using multiple sort orderings (`id`, `name`, `path`, `updated_at`, `star_count`, `last_activity_at`, `similarity`)
+2. **Branch Enumeration**: Fetching all branches for each repository via the GitLab API
+3. **Archive Download**: Downloading `.tar.gz` archives for each repository/branch combination
+4. **Content Extraction**: Extracting and filtering source code files from archives
+5. **Parquet Generation**: Writing filtered records to Parquet shards with Zstd compression
+
+### Language Detection
+
+Programming languages are detected using file extension mapping. The pipeline maps ~80 programming languages by their file extensions, including:
+- **Major languages**: Python, JavaScript, TypeScript, C, C++, C#, Java, Go, Rust, Ruby, PHP
+- **Configuration**: JSON, YAML, TOML, XML, INI
+- **Markup**: HTML, CSS, Markdown, LaTeX
+- **Game development**: GLSL, HLSL, GDScript
+- **And many more**
+
+Files with unrecognized extensions are labeled with the extension itself (without the dot prefix). Files without extensions are labeled as "none" or by special filename matching (e.g., "Dockerfile", "Makefile").
+
+### License Detection
+
+Licenses are detected by:
+1. Scanning for license files (`LICENSE`, `LICENSE.txt`, `LICENSE.md`, `COPYING`, `COPYING.txt`, `COPYING.md`)
+2. Matching license text against known patterns (MIT, Apache 2.0, GPL variants, BSD, Creative Commons, MPL, ISC, Unlicense, Artistic, WTFPL, Zlib, etc.)
+3. Defaulting to "unknown" if no license can be detected
+
+### File Filtering
+
+Filtering is applied to ensure data quality:
+
+#### Size Limits
+| Limit | Value |
+|-------|-------|
+| Max repository archive size | 64 MB |
+| Max line length | 1,000 characters |
+
+#### Content Filtering
+- **Binary Detection**: Files with null bytes in the first 1KB are excluded
+- **UTF-8 Validation**: Files must be decodable as UTF-8 (with fallback to latin-1, cp1252, iso-8859-1)
+- **Long Lines**: Files with any line exceeding 1,000 characters are excluded
+- **License Files**: License files (LICENSE, COPYING, etc.) are excluded from the dataset (but used for license detection)
+
+### Source Data
+
+All data originates from public repositories hosted on [GitGud.io](https://gitgud.io).
+
+## 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
 
-- **Format**: JSONL (JSON Lines) compressed with Zstandard (.jsonl.zst)
-- **File Structure**: 194 files (gitgud_0000.jsonl.zst to gitgud_0193.jsonl.zst)
-- **Total Repositories**: 26,610 repositories and branches
-- **Filtering**: Files with lines longer than 1,000 characters were excluded
-- **Deduplication**: No deduplication was performed on the dataset
+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.
