+# NASA Systems Engineering LLaMA-3.1 8B Instruct (Fine-Tuned)
 
-- **Developed by:** MarshallDoyle
-- **License:** apache-2.0
-- **Finetuned from model :** unsloth/meta-llama-3.1-8b-instruct-unsloth-bnb-4bit
+- **Developed by:** MarshallDoyle  
+- **License:** Apache-2.0  
+- **Fine-tuned from model:** unsloth/meta-llama-3.1-8b-instruct-unsloth-bnb-4bit  
 
-This llama model was trained 2x faster with [Unsloth](https://github.com/unslothai/unsloth) and Huggingface's TRL library.
+This model specializes in answering questions and summarizing content from NASA’s *Systems Engineering Handbook* (2018) PDF. It was fine-tuned using Hugging Face’s TRL and LoRA techniques for high efficiency.

+## Preview of Fine-Tuning Source
+
+![Preview of NASA Systems Engineering Handbook first page](https://www.nasa.gov/sites/default/files/atoms/files/nasa_systems_engineering_handbook_0.pdf#page=1)
+
+*(Above: the front page of the NASA Systems Engineering Handbook used for fine-tuning.)*

+
+## Overview
+
+**Key Features:**
+
+- **Domain Expertise:** Deep understanding of NASA systems engineering lifecycle phases, verification vs. validation testing, and SE best practices.  
+- **Compact Footprint:** Keeps the lightweight 8B base model, adding only ~83.8M trainable parameters via LoRA.  
+- **Extended Context:** Supports up to 128K tokens for long-form document Q&A.  
+
+**Intended Use:** Ideal for educational tools, engineering Q&A assistants, mission planning support, and rapid handbook lookup.

+## Model Card Updates
+
+- Removed Unsloth branding badges in favor of a direct preview of the NASA PDF source.  
+- Added a representative image of the handbook’s first page to illustrate the training data.
