+### Local LLM Support (Ollama)
+
+**Privacy-First by Default**: Cortex uses local LLMs via Ollama for zero-cost, offline-capable operation.
+
+**Benefits:**
+- ✅ **100% Private**: All processing happens locally
+- ✅ **Completely Offline**: Works without internet after setup
+- ✅ **Zero Cost**: No API fees or subscriptions
+- ✅ **No API Keys**: Get started immediately
+
+**Recommended Models:**
+- `phi3:mini` (1.9GB) - Lightweight, default
+- `llama3:8b` (4.7GB) - Balanced performance
+- `codellama:13b` (9GB) - Code-optimized
+- `deepseek-coder-v2:16b` (10GB+) - Best for system tasks
+
+**Manage Models:**
+```bash
+ollama list                     # Show installed models
+ollama pull llama3:8b          # Download a model
+ollama rm phi3:mini            # Remove a model
+```
+
+**Cloud Fallback:**
+If local models are unavailable, Cortex automatically falls back to cloud providers (if configured):
+```bash
+# Optional: Set cloud API keys for fallback
+export ANTHROPIC_API_KEY=your-claude-key
+export OPENAI_API_KEY=your-openai-key
+```

+# Automatic Ollama Setup During Installation
+
+## Overview
+
+Cortex Linux now automatically sets up Ollama during the `pip install` process, making it easier to get started with local LLM support without manual configuration.
+
+## How It Works
+
+When you run `pip install -e .` (development mode) or `pip install cortex-linux` (production), the installation process automatically:
+
+1. **Downloads and installs Ollama** - The official Ollama binary is downloaded and installed system-wide
+2. **Starts the Ollama service** - The Ollama daemon is started in the background
+3. **Prompts for model selection** - Interactive prompt to choose and download an LLM model (e.g., codellama:7b, phi3:mini)
+
+## Installation Behavior
+
+### Normal Installation
+```bash
+pip install -e .
+```
+
+This will:
+- Install all Python dependencies
+- Run the Ollama setup script automatically
+- Prompt you to select a model to download
+- Complete the setup with no additional steps needed
+
+### CI/Automated Environments
+
+The setup automatically detects and skips Ollama installation in:
+- CI environments (checks `CI` or `GITHUB_ACTIONS` environment variables)
+- Non-interactive terminals (skips model download prompt)
+
+### Manual Skip
+
+To skip Ollama setup during installation:
+```bash
+CORTEX_SKIP_OLLAMA_SETUP=1 pip install -e .
+```
+
+## Architecture
+
+### Flow Diagram
+
+```
+pip install -e .
+    ├─> setuptools installs dependencies
+    ├─> setuptools installs entry points (cortex, cortex-setup-ollama)
+    └─> PostDevelopCommand.run() is triggered
+        └─> imports scripts.setup_ollama
+            └─> setup_ollama() executes
+                ├─> Check skip flags (CORTEX_SKIP_OLLAMA_SETUP, CI)
+                ├─> install_ollama()
+                │   ├─> Check if already installed
+                │   └─> Download and run install.sh
+                ├─> start_ollama_service()
+                │   └─> Start 'ollama serve' in background
+                └─> prompt_model_selection() (if interactive)
+                    └─> pull_selected_model()
+```
+
+## Testing
+
+### Run Integration Tests
+```bash
+python3 tests/test_ollama_setup_integration.py
+```
+
+This validates:
+- Package structure is correct
+- MANIFEST.in includes scripts directory
+- setup_ollama can be imported
+- setup_ollama executes without errors
+
+### Manual Testing
+```bash
+# Test with skip flag
+CORTEX_SKIP_OLLAMA_SETUP=1 pip install -e .
+
+# Test normal installation (requires interactive terminal)
+pip install -e .
+
+# Verify Ollama was installed
+which ollama
+ollama --version
+
+# Verify cortex works with Ollama
+cortex install nginx --dry-run
+```
+
+## Troubleshooting
+
+### Ollama Setup Fails During Installation
+
+If Ollama setup fails, the installation will still succeed with a warning:
+```
+⚠️  Ollama setup encountered an issue: [error message]
+ℹ️  You can run it manually later with: cortex-setup-ollama
+```
+
+You can then manually run:
+```bash
+cortex-setup-ollama
+```
+
+### Permission Issues
+
+Ollama installation requires sudo access. If you get permission errors:
+1. Run with sudo: `sudo pip install -e .` (not recommended)
+2. Or skip Ollama during install and run manually:
+   ```bash
+   CORTEX_SKIP_OLLAMA_SETUP=1 pip install -e .
+   sudo cortex-setup-ollama
+   ```
+
+### Ollama Already Installed
+
+The setup script detects if Ollama is already installed and skips the installation step:
+```
+✅ Ollama already installed
+```
+
+## Configuration
+
+### Environment Variables
+
+- `CORTEX_SKIP_OLLAMA_SETUP=1` - Skip Ollama setup entirely
+- `CI=1` or `GITHUB_ACTIONS=true` - Automatically detected, skips setup
+
+### Available Models
+
+During interactive installation, you can choose from:
+1. **codellama:7b** (3.8 GB) - Default, good for code
+2. **llama3:8b** (4.7 GB) - Balanced, general purpose
+3. **phi3:mini** (1.9 GB) - Lightweight, quick responses
+4. **deepseek-coder:6.7b** (3.8 GB) - Code-optimized
+5. **mistral:7b** (4.1 GB) - Fast and efficient
+6. **Skip** - Download later with `ollama pull <model>`
+
+## Command Reference
+
+### Installed Commands
+
+After installation, these commands are available:
+
+```bash
+# Main Cortex CLI
+cortex install nginx
+
+# Manually run Ollama setup
+cortex-setup-ollama
+```
+
+### Manual Ollama Commands
+
+```bash
+# Check Ollama status
+ollama --version
+
+# Start Ollama service
+ollama serve
+
+# Pull a specific model
+ollama pull codellama:7b
+
+# List downloaded models
+ollama list
+
+# Remove a model
+ollama rm codellama:7b
+```
+
+## Development Notes
+
+### Why This Approach?
+
+1. **User Experience** - Zero-configuration setup for local LLM support
+2. **Optional** - Can be skipped with environment variable
+3. **Safe** - Detects CI environments automatically
+4. **Robust** - Gracefully handles failures, doesn't break installation
+5. **Standard** - Uses setuptools' cmdclass hooks (standard Python packaging)
+
+### Alternative Approaches Considered
+
+1. **Post-install script in entry_points** - Less reliable, harder to control execution context
+2. **Separate install command** - Requires manual step, worse UX
+3. **Check on first run** - Delays first use, interrupts workflow
+4. **Docker-only** - Limits flexibility, requires container runtime
+
+### Future Enhancements
+
+- [ ] Add progress bar for Ollama download
+- [ ] Support for custom model selection via environment variable
+- [ ] Ollama version pinning/updates
+- [ ] Automatic model updates on new Cortex releases
+- [ ] Integration with `cortex doctor` for Ollama health checks

+# Automatic Ollama Setup - Implementation Summary
+
+## Overview
+
+Implemented automatic Ollama installation and setup during `pip install -e .` (or `pip install cortex-linux`). This eliminates the need for manual Ollama installation and provides a seamless onboarding experience for users.
+
+## Changes Made
+
+### 1. Created `scripts/__init__.py`
+**File:** [scripts/__init__.py](../scripts/__init__.py)
+
+- Makes the `scripts` directory a proper Python package
+- Enables import of `setup_ollama` module from within setuptools hooks
+- Simple docstring-only file
+
+### 2. Modified `setup.py`
+**File:** [setup.py](../setup.py)
+
+**Changes:**
+- Updated `PostInstallCommand.run()` to import and call `setup_ollama()` directly instead of using subprocess
+- Updated `PostDevelopCommand.run()` to import and call `setup_ollama()` directly instead of using subprocess
+- Changed error messages to reference `cortex-setup-ollama` command instead of Python script path
+
+**Before:**
+```python
+subprocess.run([sys.executable, "scripts/setup_ollama.py"], check=False)
+```
+
+**After:**
+```python
+from scripts.setup_ollama import setup_ollama
+setup_ollama()
+```
+
+**Benefits:**
+- More reliable - no subprocess overhead or path resolution issues
+- Better error handling - Python exceptions instead of exit codes
+- Works in all installation contexts (pip, pip -e, setup.py install)
+
+### 3. Updated `MANIFEST.in`
+**File:** [MANIFEST.in](../MANIFEST.in)
+
+**Changes:**
+- Added `recursive-include scripts *.py` to include all Python files in scripts directory
+- Ensures scripts package is included in distribution
+
+**Before:**
+```
+include README.md
+include LICENSE
+recursive-include LLM *.py
+recursive-include cortex *.py
+include LLM/requirements.txt
+```
+
+**After:**
+```
+include README.md
+include LICENSE
+recursive-include LLM *.py
+recursive-include cortex *.py
+recursive-include scripts *.py
+include LLM/requirements.txt
+```
+
+### 4. Fixed `pyproject.toml`
+**File:** [pyproject.toml](../pyproject.toml)
+
+**Changes:**
+- Fixed license field format from `license = "Apache-2.0"` to `license = {text = "Apache-2.0"}`
+- Resolves setuptools warning about license format
+
+### 5. Created Integration Tests
+**File:** [tests/test_ollama_setup_integration.py](../tests/test_ollama_setup_integration.py)
+
+**Purpose:**
+- Validates package structure is correct
+- Tests that `setup_ollama` can be imported
+- Tests that `setup_ollama()` executes without errors
+- Verifies MANIFEST.in configuration
+
+**Run with:**
+```bash
+python3 tests/test_ollama_setup_integration.py
+```
+
+### 6. Created Verification Script
+**File:** [scripts/verify_ollama_setup.sh](../scripts/verify_ollama_setup.sh)
+
+**Purpose:**
+- Shell script for quick verification of all components
+- Runs multiple checks in sequence
+- Provides clear pass/fail output
+- Includes next steps and documentation references
+
+**Run with:**
+```bash
+./scripts/verify_ollama_setup.sh
+```
+
+### 7. Created Comprehensive Documentation
+**File:** [docs/AUTOMATIC_OLLAMA_SETUP.md](../docs/AUTOMATIC_OLLAMA_SETUP.md)
+
+**Contents:**
+- Overview of the feature
+- How it works (architecture, flow diagram)
+- Installation behavior (normal, CI, manual skip)
+- Testing instructions
+- Troubleshooting guide
+- Configuration options
+- Command reference
+- Development notes
+

+
+### Safety Features
+
+1. **CI Detection** - Automatically skips in CI/CD environments
+2. **Skip Flag** - `CORTEX_SKIP_OLLAMA_SETUP=1` to manually skip
+3. **Graceful Failure** - Installation succeeds even if Ollama fails
+4. **Non-Interactive Mode** - Skips model prompt in non-TTY terminals
+5. **Existing Installation** - Detects and skips if Ollama already installed
+
+## Testing
+
+### Verification Results
+
+```bash
+./scripts/verify_ollama_setup.sh
+```
+
+✅ All 6 checks pass:
+1. Package structure (scripts/__init__.py, setup_ollama.py)
+2. MANIFEST.in configuration
+3. Import test
+4. Execution test (skipped mode)
+5. Integration tests
+6. setup.py validation
+
+### Integration Test Results
+
+```bash
+python3 tests/test_ollama_setup_integration.py
+```
+
+✅ All 4 tests pass:
+1. Package Structure
+2. MANIFEST.in Configuration
+3. Setup Import
+4. Setup Execution
+
+## Usage Examples
+
+### Normal Installation (Full Setup)
+```bash
+pip install -e .
+# Ollama will be automatically installed and configured
+```
+
+### Skip Ollama During Installation
+```bash
+CORTEX_SKIP_OLLAMA_SETUP=1 pip install -e .
+# Ollama setup is skipped, can run manually later
+```
+
+### Manual Ollama Setup
+```bash
+# After installation with skip flag
+cortex-setup-ollama
+```
+
+### Check Ollama Status
+```bash
+# Verify Ollama was installed
+which ollama
+ollama --version
+ollama list
+
+# Test Cortex with Ollama
+cortex install nginx --dry-run
+```
+
+## Environment Variables
+

+# Quick Reference: Ollama Auto-Setup
+
+## ✅ What Was Implemented
+
+Ollama is now **automatically installed** when you run `pip install -e .`
+
+## 🚀 Usage
+
+### Normal Installation (Ollama Included)
+```bash
+pip install -e .
+```
+- Installs Cortex
+- Downloads and installs Ollama binary
+- Starts Ollama service
+- Prompts for model selection (e.g., codellama:7b)
+- Takes ~5-10 minutes (mostly model download)
+
+### Skip Ollama During Installation
+```bash
+CORTEX_SKIP_OLLAMA_SETUP=1 pip install -e .
+```
+- Installs Cortex only
+- Skips Ollama setup
+- Faster installation
+- Can set up Ollama manually later
+
+### Manual Ollama Setup (After Installation)
+```bash
+cortex-setup-ollama
+```
+- Run this if you skipped Ollama during installation
+- Or to re-run the setup/add models
+
+## 🔍 Verification
+
+### Check Installation
+```bash
+# Verify Ollama binary
+which ollama
+ollama --version
+
+# List downloaded models
+ollama list
+
+# Test Cortex with Ollama
+cortex install nginx --dry-run
+```
+
+### Run Tests
+```bash
+# Integration tests
+python3 tests/test_ollama_setup_integration.py
+
+# Full verification
+./scripts/verify_ollama_setup.sh

+# OR skip during install, then:
+CORTEX_SKIP_OLLAMA_SETUP=1 pip install -e .
+sudo cortex-setup-ollama
+```
+
+### Check What Happened
+```bash
+# During install, you'll see:
+# ✅ Ollama already installed (if already present)
+# 📦 Installing Ollama... (if downloading)
+# ⏭️  Skipping Ollama setup (if skipped)

+
+# Uses Ollama by default, falls back to cloud if needed
+cortex install complex-package
+```
+
+### Manual Model Management
+```bash
+# List models
+ollama list
+
+# Pull specific model
+ollama pull llama3:8b
+
+# Remove model
+ollama rm old-model
+```
+
+### Python API
+```python
+from cortex.providers.ollama_provider import OllamaProvider
+from cortex.llm_router import LLMRouter
+
+# Direct Ollama usage
+ollama = OllamaProvider()
+response = ollama.complete(
+    messages=[{"role": "user", "content": "Install nginx"}]
+)
+
+# Router with auto-fallback
+router = LLMRouter(prefer_local=True)
+response = router.complete(
+    messages=[{"role": "user", "content": "Install nginx"}],
+    task_type=TaskType.SYSTEM_OPERATION
+)
+```
+
+## Configuration
+
+### Environment Variables
+```bash
+OLLAMA_HOST=http://localhost:11434  # Ollama API URL
+CORTEX_SKIP_OLLAMA_SETUP=1          # Skip auto-setup
+ANTHROPIC_API_KEY=...               # Claude fallback
+OPENAI_API_KEY=...                  # OpenAI fallback
+```
+
+### Config File (`~/.cortex/config.yaml`)
+```yaml
+llm:
+  prefer_local: true
+  ollama:
+    enabled: true
+    base_url: http://localhost:11434
+    preferred_models:
+      - deepseek-coder-v2:16b
+      - llama3:8b
+    auto_pull: true
+  claude:
+    enabled: false
+  kimi_k2:
+    enabled: false
+```
+
+## Performance Considerations
+
+### Model Size vs Performance
+| Model | Size | Speed | Quality | Use Case |
+|-------|------|-------|---------|----------|
+| phi3:mini | 1.9GB | Fast | Good | Default, testing |
+| llama3:8b | 4.7GB | Medium | V.Good | Balanced usage |
+| codellama:13b | 9GB | Medium | Excellent | Code tasks |
+| deepseek-coder-v2:16b | 10GB+ | Slower | Outstanding | Complex code |
+
+### Hardware Requirements
+- **Minimum:** 8GB RAM, 4 cores, 5GB disk
+- **Recommended:** 16GB RAM, 8 cores
+- **Optimal:** 32GB RAM, GPU with 8GB+ VRAM
+
+## Testing
+
+### Unit Tests
+```bash
+pytest tests/test_ollama_integration.py -v
+```
+
+### Manual Testing
+```bash
+# Run demo
+python examples/ollama_demo.py
+
+# Test installation
+cortex install test-package --dry-run
+```
+
+## Known Limitations
+
+1. **First Model Pull:** Takes 5-10 minutes depending on internet speed
+2. **Large Models:** Require significant RAM (8-16GB+)
+3. **CPU Inference:** Slower than GPU (but still usable)
+4. **Linux Only:** Ollama primarily targets Linux (macOS also supported)
+
+## Future Enhancements
+
+1. **GPU Acceleration:** Auto-detect and utilize CUDA/ROCm
+2. **Model Caching:** Cache frequently used model outputs
+3. **Quantization:** Support for smaller quantized models
+4. **Model Recommendations:** Suggest models based on hardware
+5. **Batch Processing:** Batch multiple requests for efficiency
+6. **Custom Models:** Support for user-trained models
+
+## Security Considerations
+
+### Data Privacy
+- ✅ All processing happens locally
+- ✅ No network calls during inference
+- ✅ No logging of prompts/responses
+- ✅ Models stored in `~/.ollama` (user-owned)
+
+### System Security
+- ✅ Runs in user space (no root required)
+- ✅ Sandboxed model execution
+- ✅ No elevated privileges needed
+
+## Comparison: Before vs After
+
+### Before (Cloud-Only)
+```bash
+# Required API key
+export ANTHROPIC_API_KEY=sk-...
+
+# Cost: $3-15 per 1M tokens
+# Privacy: Data sent to cloud
+# Offline: Not possible
+```
+
+### After (Ollama Default)
+```bash
+# No API key needed!
+
+# Cost: $0.00
+# Privacy: 100% local
+# Offline: Fully functional
+```
+
+## Migration Guide
+
+### Existing Users
+No breaking changes! Existing configurations work as-is.
+
+```bash
+# Still works with API keys
+export ANTHROPIC_API_KEY=sk-...
+cortex install nginx
+
+# Now also works without API keys
+unset ANTHROPIC_API_KEY
+cortex install nginx  # Uses Ollama automatically
+```

+# Ollama Integration - Local LLM Support
+
+## Overview
+
+Cortex Linux now supports **local LLM inference** via Ollama, enabling privacy-first, offline-capable package management without requiring cloud API keys.
+
+## Key Features
+
+✅ **Privacy-First**: All processing happens locally, zero data sent to cloud  
+✅ **Offline Capable**: Works completely offline once models are downloaded  
+✅ **Zero Cost**: No API keys or subscriptions required  
+✅ **Auto-Setup**: Automatically installed and configured during `pip install`  
+✅ **Smart Fallback**: Falls back to Claude/OpenAI if local models unavailable  
+✅ **Code-Optimized**: Prefers code-focused models for system tasks  
+✅ **Streaming Support**: Real-time response streaming  
+
+## Quick Start
+
+### 1. Install Cortex with Ollama
+
+```bash
+# Clone repository
+git clone https://github.com/cortexlinux/cortex.git
+cd cortex
+
+# Install (automatically sets up Ollama)
+python3 -m venv venv
+source venv/bin/activate
+pip install -e .
+```
+
+During installation, Cortex will:
+- Install Ollama (if not already present)
+- Start the Ollama service
+- Pull a lightweight default model (`phi3:mini`)
+
+### 2. Use Cortex Without API Keys
+
+```bash
+# Install packages using local LLM
+cortex install nginx
+
+# No ANTHROPIC_API_KEY or OPENAI_API_KEY needed!
+```
+
+### 3. Check Ollama Status
+
+```bash
+# Verify Ollama is running
+ollama list
+
+# See available models
+ollama ps
+```
+
+## How It Works
+
+### Architecture
+
+```

+    ↓
+LLM Router (cortex/llm_router.py)
+    ↓
+Provider Selection:
+    1. Ollama (Local) - Priority 1
+    2. Claude (Cloud) - Fallback 1
+    3. Kimi K2 (Cloud) - Fallback 2
+    ↓
+Response to User
+```
+
+### Model Selection
+
+Cortex automatically selects the best available model:
+
+**Preferred Models** (code-optimized):
+1. `deepseek-coder-v2:16b` - Best for code and system tasks
+2. `codellama:13b` - Meta's code-specialized model
+3. `deepseek-coder:6.7b` - Good balance of speed/quality
+4. `llama3:8b` - General purpose, very capable
+5. `mistral:7b` - Fast and efficient
+6. `phi3:mini` - Lightweight (default)
+
+### Privacy Guarantees
+
+- **100% Local**: Models run on your machine
+- **No Telemetry**: Ollama doesn't send usage data
+- **No Internet Required**: Works offline after model download
+- **No API Keys**: No credentials to manage or expose
+
+## Configuration
+
+### Environment Variables
+
+```bash
+# Ollama settings
+export OLLAMA_HOST=http://localhost:11434  # Default
+export CORTEX_SKIP_OLLAMA_SETUP=1          # Skip auto-setup
+
+# Cloud fallbacks (optional)
+export ANTHROPIC_API_KEY=your-claude-key
+export OPENAI_API_KEY=your-openai-key
+```
+
+### Configuration File
+

+
+## Troubleshooting
+
+### Ollama Not Starting
+
+```bash
+# Check if service is running
+systemctl status ollama
+
+# Start manually
+ollama serve &
+
+# Check logs
+journalctl -u ollama -f
+```
+
+### Models Not Downloading
+
+```bash
+# Check disk space
+df -h
+
+# Check network
+curl -I https://ollama.com
+
+# Pull specific version
+ollama pull llama3:8b-q4_0
+```
+
+### Slow Responses
+
+```bash
+# Use smaller model
+ollama pull phi3:mini
+
+# Check system resources
+htop
+
+# Enable GPU acceleration (if available)
+# Ollama auto-detects CUDA/ROCm
+```
+
+### Fallback to Cloud
+
+```bash
+# Set API keys for fallback
+export ANTHROPIC_API_KEY=your-key
+
+# Or disable Ollama temporarily
+export OLLAMA_HOST=http://invalid
+```
+
+## API Reference
+
+### OllamaProvider Class
+
+```python
+from cortex.providers.ollama_provider import OllamaProvider
+
+# Initialize
+ollama = OllamaProvider(
+    base_url="http://localhost:11434",
+    timeout=300,
+    auto_pull=True
+)
+
+# Check installation
+if ollama.is_installed():
+    print("✅ Ollama available")
+
+# Ensure service running
+ollama.start_service()
+
+# Get available models
+models = ollama.get_available_models()
+
+# Generate completion
+response = ollama.complete(
+    messages=[
+        {"role": "user", "content": "Explain nginx configuration"}
+    ],
+    temperature=0.7,
+    max_tokens=2048
+)
+```
+
+### LLM Router Integration
+
+```python
+from cortex.llm_router import LLMRouter, LLMProvider, TaskType
+
+# Initialize router (auto-detects Ollama)
+router = LLMRouter(prefer_local=True)
+
+# Complete with auto-routing
+response = router.complete(
+    messages=[{"role": "user", "content": "Install nginx"}],
+    task_type=TaskType.SYSTEM_OPERATION
+)
+
+# Force Ollama
+response = router.complete(
+    messages=[...],
+    force_provider=LLMProvider.OLLAMA
+)
+```
+
+## Comparison: Local vs Cloud
+
+| Feature | Ollama (Local) | Claude | Kimi K2 |
+|---------|---------------|--------|---------|
+| **Privacy** | 100% local | Cloud | Cloud |
+| **Cost** | Free | $3-15/1M tokens | $1-5/1M tokens |
+| **Speed** | Depends on hardware | Fast | Fast |
+| **Offline** | ✅ Yes | ❌ No | ❌ No |
+| **Setup** | Auto | API key | API key |
+| **Quality** | Good-Excellent | Excellent | Excellent |
+
+## Best Practices
+
+### When to Use Ollama
+
+✅ Privacy-sensitive operations  
+✅ Offline environments  
+✅ Development/testing  
+✅ Cost-sensitive workloads  
+✅ Repeated similar tasks  
+
+### When to Use Cloud
+
+✅ Maximum quality needed  
+✅ Complex reasoning tasks  
+✅ Limited local resources  
+✅ Infrequent usage  
+
+### Hybrid Approach
+
+```python
+# Use Ollama for common tasks
+router = LLMRouter(prefer_local=True)
+
+# Explicit cloud for complex tasks
+response = router.complete(
+    messages=[...],
+    force_provider=LLMProvider.CLAUDE,
+    task_type=TaskType.ERROR_DEBUGGING
+)
+```
+
+## Security Considerations
+
+### Data Privacy
+
+- **Local Processing**: All LLM inference happens locally
+- **No Logging**: Ollama doesn't log prompts or responses
+- **No Network**: Zero network calls during inference
+
+### System Security
+
+- **Sandboxed**: Ollama runs in user space
+- **No Root**: Doesn't require elevated privileges
+- **Isolated**: Models stored in `~/.ollama`
+
+### API Key Safety
+
+- **Optional**: API keys only needed for cloud fallback
+- **Encrypted**: Stored securely in system keyring
+- **Never Logged**: Keys never written to logs
+
+## Contributing
+
+### Adding New Models
+
+1. Test model compatibility:
+```bash
+ollama pull your-model:tag
+cortex install test-package --dry-run
+```
+
+2. Update preferred models in [ollama_provider.py](../cortex/providers/ollama_provider.py)
+
+3. Document in this guide
+
+### Reporting Issues
+
+Include in bug reports:
+- `ollama --version`
+- `cortex --version`
+- Model being used
+- Hardware specs
+- Error logs

+
+**Q: Can I use multiple models?**  
+A: Yes, Cortex auto-selects based on availability and task type.
+
+**Q: Is it really private?**  
+A: Yes - 100% local processing, no telemetry, no internet required after setup.
+
+**Q: How do I update models?**  
+A: `ollama pull model-name` downloads the latest version.
+
+**Q: Can I disable Ollama?**  
+A: Set `CORTEX_SKIP_OLLAMA_SETUP=1` or remove API keys to force cloud usage.

+# ✓ Ready to use!
+```
+
+## 🏗️ Architecture
+
+### Provider Layer
+```python
+class OllamaProvider:
+    - is_installed() → bool
+    - start_service() → bool
+    - get_available_models() → list[str]
+    - select_best_model() → str
+    - pull_model(name: str) → bool
+    - complete(messages, ...) → dict
+```
+
+### Router Integration
+```python
+class LLMRouter:
+    ROUTING_RULES = {
+        TaskType.SYSTEM_OPERATION: LLMProvider.OLLAMA,
+        TaskType.CODE_GENERATION: LLMProvider.OLLAMA,
+        # ... all tasks default to Ollama
+    }
+```
+
+### Fallback Logic
+```python
+if routing.provider == OLLAMA and not available:
+    fallback = CLAUDE if claude_api_key else KIMI_K2
+```
+
+## 📊 Performance

+## 🔄 Migration Guide
+
+### For Existing Users
+**No breaking changes!** Existing configurations work as-is.
+
+```bash
+# Still works with API keys
+export ANTHROPIC_API_KEY=sk-...
+cortex install nginx
+
+# Now also works without
+cortex install nginx  # Uses Ollama automatically
+```
+
+### For New Users
+```bash
+# 1. Install
+pip install -e .
+
+# 2. Use immediately (no setup needed)
+cortex install nginx --dry-run
+```
+
+## 🎨 Configuration Examples
+
+### Prefer Local
+```yaml
+llm:
+  prefer_local: true
+  ollama:
+    enabled: true
+    preferred_models:
+      - deepseek-coder-v2:16b
+```
+
+### Cloud Fallback
+```yaml
+llm:
+  prefer_local: true
+  ollama:
+    enabled: true
+  claude:
