+# Offline Models
+
+Brainy uses Transformers.js with ONNX Runtime for **true offline operation** - no more TensorFlow.js dependency hell!
+
+## How it works
+
+Brainy automatically figures out the best approach:
+
+1. **First use**: Downloads models once (~87 MB) to local cache
+2. **Subsequent use**: Loads from cache (completely offline, zero network calls)  
+3. **Smart detection**: Automatically finds models in cache, bundled, or downloads as needed
+
+## Standard usage
+
+```bash
+npm install @soulcraft/brainy
+# Use immediately - models download automatically on first use
+```
+
+## Docker with production egress restrictions
+
+For environments where production has no internet but build does:
+
+```dockerfile
+FROM node:24-slim
+WORKDIR /app
+COPY package*.json ./
+RUN npm install @soulcraft/brainy
+RUN npm run download-models  # Download during build (when internet available)
+COPY . .
+# Production container now works completely offline
+```
+
+## Development with immediate offline
+
+If you want models available immediately for development:
+
+```bash
+npm install @soulcraft/brainy
+npm run download-models  # Optional: download now instead of on first use
+```
+
+## Key benefits vs TensorFlow.js
+
+- ✅ **95% smaller package** - 643 kB vs 12.5 MB  
+- ✅ **84% smaller models** - 87 MB vs 525 MB
+- ✅ **True offline** - Zero network calls after initial download
+- ✅ **No dependency issues** - 5 deps vs 47+, no more --legacy-peer-deps
+- ✅ **Better performance** - ONNX Runtime beats TensorFlow.js
+- ✅ **Same API** - Drop-in replacement
+
+## Philosophy
+
+**Install and use. Brainy handles the rest.**
+
+No configuration files, no environment variables, no complex setup. Brainy detects your environment and does the right thing automatically.
