+# C, C++, and Docs Training Dataset
+
+A massive, multi-format code and documentation corpus built from 70+ major open-source C/C++ repositories (including the Linux kernel, FFmpeg, SQLite, Git, Redis, and Vulkan/FreeType headers).
+
+## Dataset Structure
+
+The dataset is processed using a sliding-window text chunking method (350-word chunks with a 50-word overlap) to preserve function boundaries, variable scopes, and multi-line logic blocks while maximizing long-range structural context.
+
+Each record in the JSONL and Parquet shards contains:
+- **`id`**: Unique identifier for the chunk.
+- **`source`**: Originating source file path (`C_data.txt`, `Cpp.txt`, or `text.txt`).
+- **`category`**: Content classification tag (`c`, `cpp`, or `docs`).
+- **`chunk_index`**: Sequential index within the source file.
+- **`content`**: Raw text block of source code or documentation.
+
+## Corpus Breakdown
+- **C Source Code (`C_data.txt`)**: ~5.5M lines of low-level systems code, headers, and core utilities.
+- **C++ Source Code (`Cpp.txt`)**: ~1.3M lines of modern C++ templates, wrappers, and library implementations.
+- **Documentation & Text (`text.txt`)**: ~8M lines of markdown files, specs, and configuration manuals.
