+## 🚀 Source-to-Image (S2I) Support
+
+ORU Analyzer now supports **Source-to-Image (S2I)** deployment as an alternative to container-based deployment.
+
+### S2I Benefits
+- ⚡ **Faster deployment** - Direct from Git repository
+- 🔄 **Automatic rebuilds** - When code changes
+- 🎯 **No external registry** - OpenShift manages everything
+- 🔧 **Simpler CI/CD** - No GitHub Actions + Quay.io needed
+
+### S2I vs Container Build
+
+| Feature | S2I | Container Build |
+|---------|-----|-----------------|
+| **Deployment Speed** | ⚡ Fast | 🐌 Slower |
+| **Auto Rebuilds** | ✅ Yes | ❌ No |
+| **Git Integration** | ✅ Native | ❌ Manual |
+| **Registry Dependency** | ❌ None | ✅ Quay.io |
+| **Build Control** | 🔒 Limited | 🎛️ Full Control |
+
+### S2I Quick Start
+```bash
+# Deploy using S2I
+./scripts/deploy-s2i.sh
+
+# Or use oc new-app
+oc new-app python:3.11~https://github.com/andersonid/openshift-resource-governance.git \
+  --name=oru-analyzer --env=PYTHON_VERSION=3.11
+```
