+# 🧠 BitNet CPU Assistant
+
+Run Microsoft's 1-bit LLMs at lightning speeds on standard CPUs.
+
+## Features
+- **1-bit Inference**: Powered by `bitnet.cpp` for maximum efficiency.
+- **CPU Optimized**: No GPU required, perfect for free-tier hosting.
+- **Low Memory**: 3B models run in under 4GB of RAM.
+
+## Deployment Instructions
+1. Create a new Streamlit Space on Hugging Face.
+2. Upload all files from this directory.
+3. The Space will automatically install dependencies from `packages.txt` and `requirements.txt`.
+4. The first run will compile the BitNet kernels (approx 3-5 mins).
+
+## Local Development
+```bash
+pip install -r requirements.txt
+streamlit run app.py
+```
