 ## Recommended Workflow
 
+### Non-Git Deployment (wget/extract without git)
+```bash
+# 1. Download and extract fresh code
+wget https://your-repo-url/archive.tar.gz
+tar -xzf archive.tar.gz
+
+# 2. If updating in same directory, clear old cache
+bash launcher.sh --clear-cache
+
+# 3. Run fresh detection
+bash launcher.sh --detect-only
+
+# 4. Run normally
+bash launcher.sh
+```
+
+**Note**: Cache files are NOT included in download archives (excluded via .gitignore), so fresh extracts always start clean.
