+# KernelLLM-1 Dataset
+
+A high-quality raw dataset for training and fine-tuning LLMs on Operating System Development.
+
+## Overview
+
+This dataset combines raw source code from a variety of mature and hobbyist operating system kernels with thousands of expert-level technical discussions and critiques from the Linux Kernel Mailing List. 
+
+> [!NOTE]
+> The source code included in this dataset represents the latest stable versions of the respective repositories as of **February 2nd 2026**.
+
+## Dataset Structure
+
+The dataset is provided in **Parquet** format for optimal compression and integration with the `datasets` library.
+
+### 1. `kernelllm_source.parquet` (~982 MB)
+**Cleaned & Deduplicated Source Code (180,129 files).**
+- **Sources:** Linux, FreeBSD, OpenBSD, NetBSD, Illumos, ReactOS, seL4, ToaruOS, Redox OS, SerenityOS and DragonFlyBSD.
+- **Cleaning:**
+    - Removed common license headers (GPL, BSD, MIT, etc) to prioritize logic.
+    - Exact and "smart" deduplication (normalized whitespace) across repositories.
+    - Excluded files < 100 characters to remove boilerplate headers.
+
+#### Repository Distribution:
+| Repository | File Count |
+|------------|------------|
+| Linux | 62,969 |
+| FreeBSD | 43,956 |
+| Illumos | 23,411 |
+| BSD-Mixed (Open/Net) | 22,949 |
+| DragonFlyBSD | 17,662 |
+| SerenityOS | 7,307 |
+| Redox OS | 701 |
+| ToaruOS | 609 |
+| seL4 | 565 |
+
+### 2. `kernelllm_critiques.parquet` (~3.6 MB) (Tiny bit of the LKML)
+**LKML Critique Pairs (3,135 pairs).**
+- **Sources:** `lore.kernel.org` archives.
+- **Content:** Pairs code snippets (patches) with substantive replies, critiques and NACKs from senior maintainers.
+- **Schema:**
+```json
+{
+  "source": "lkml",
+  "subject": "[PATCH] ...",
+  "code": "(The patch content)",
+  "critique": "(The maintainer feedback)",
+  "metadata": {
+    "author": "...",
+    "date": "...",
+    "thread_id": "..."
+  }
+}
+```
+
+## Dataset Release Strategy 
+
+This is the **Raw** version of the dataset. It is intended for:
+1.  **Intermediate Training:** Pre-training on high-quality systems code.
+2.  **Fine-Tuning:** Instruction-tuning models to act as "Kernel Maintainers". (Or just make them better at Kernel code.)
+3.  **Research:** Analyzing developer communication patterns in low-level systems.
+
+## Licensing and Usage
