+Check if Task Master is installed and install it if needed.
+
+This command helps you get Task Master set up globally on your system.
+
+## Detection and Installation Process
+
+1. **Check Current Installation**
+   ```bash
+   # Check if task-master command exists
+   which task-master || echo "Task Master not found"
+   
+   # Check npm global packages
+   npm list -g task-master-ai
+   ```
+
+2. **System Requirements Check**
+   ```bash
+   # Verify Node.js is installed
+   node --version
+   
+   # Verify npm is installed  
+   npm --version
+   
+   # Check Node version (need 16+)
+   ```
+
+3. **Install Task Master Globally**
+   If not installed, run:
+   ```bash
+   npm install -g task-master-ai
+   ```
+
+4. **Verify Installation**
+   ```bash
+   # Check version
+   task-master --version
+   
+   # Verify command is available
+   which task-master
+   ```
+
+5. **Initial Setup**
+   ```bash
+   # Initialize in current directory
+   task-master init
+   ```
+
+6. **Configure AI Provider**
+   Ensure you have at least one AI provider API key set:
+   ```bash
+   # Check current configuration
+   task-master models --status
+   
+   # If no API keys found, guide setup
+   echo "You'll need at least one API key:"
+   echo "- ANTHROPIC_API_KEY for Claude"
+   echo "- OPENAI_API_KEY for GPT models"
+   echo "- PERPLEXITY_API_KEY for research"
+   echo ""
+   echo "Set them in your shell profile or .env file"
+   ```
+
+7. **Quick Test**
+   ```bash
+   # Create a test PRD
+   echo "Build a simple hello world API" > test-prd.txt
+   
+   # Try parsing it
+   task-master parse-prd test-prd.txt -n 3
+   ```
+
+## Troubleshooting
+
+If installation fails:
+
+**Permission Errors:**
+```bash
+# Try with sudo (macOS/Linux)
+sudo npm install -g task-master-ai
+
+# Or fix npm permissions
+npm config set prefix ~/.npm-global
+export PATH=~/.npm-global/bin:$PATH
+```
+
+**Network Issues:**
+```bash
+# Use different registry
+npm install -g task-master-ai --registry https://registry.npmjs.org/
+```
+
+**Node Version Issues:**
+```bash
+# Install Node 20+ via nvm
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+nvm install 20
+nvm use 20
+```
+
+## Success Confirmation
+
+Once installed, you should see:
+```
+✅ Task Master v0.16.2 (or higher) installed
+✅ Command 'task-master' available globally
+✅ AI provider configured
+✅ Ready to use slash commands!
+
+Try: /project:task-master:init your-prd.md
+```
+
+## Next Steps
+
+After installation:
+1. Run `/project:utils:check-health` to verify setup
+2. Configure AI providers with `/project:task-master:models`
+3. Start using Task Master commands!
