  - Updated all file references to match actual project structure
  - Corrected namespace references in all Tekton manifests
  - Added accurate directory structure documentation

- **Legacy Cleanup:**

+- **Pipeline & Tasks**: Deployed in user's namespace
 - **Resources**: Prefixed with username (e.g., `alice-ollama`, `bob-ci-analysis-agent`)
 - **Routes**: Individual URLs for each deployment
 - **Storage**: Isolated persistent volumes

 ### Automated Deployment:
 The pipeline supports GitHub webhooks for automatic deployment on code pushes from any repository. The webhook endpoint automatically creates user-specific deployments based on the repository owner.

+**Automated Deployment (Recommended):**
 ```bash
-# Deploy to Kubernetes
-chmod +x deploy/deploy.sh
-./deploy/deploy.sh
+# Deploy pipeline for a specific user
+cd deploy/tekton
+chmod +x deploy-user-namespace.sh
+./deploy-user-namespace.sh <username>
 
-# Cleanup
-chmod +x deploy/cleanup.sh
-./deploy/cleanup.sh
+# Example: Deploy for user "alice"
+./deploy-user-namespace.sh alice
 ```
 
-### For OpenShift 4.19+
-
-```bash
-# Deploy to OpenShift
-chmod +x deploy/deploy-openshift.sh
-./deploy/deploy-openshift.sh
+### **User-Namespace Architecture**
 
-# Cleanup
-chmod +x deploy/cleanup-openshift.sh
-./deploy/cleanup-openshift.sh
-```
+Each user gets their own isolated deployment:
+- **Namespace**: `ci-analysis-<username>`
+- **Complete Isolation**: All resources deployed per user
+- **No Shared Infrastructure**: Every user has their own pipeline stack
+- **Automatic GitHub Integration**: Webhook-triggered deployments
 
 ## 📋 Prerequisites
 
+- **OpenShift 4.19+** or **Kubernetes 1.25+**
+- **Tekton Pipelines** installed on cluster
+- **Tekton Triggers** installed on cluster
 - **Node Architecture**: linux/amd64 nodes (required for Ollama)
-- Docker/Podman for building images
-- kubectl (for Kubernetes) or oc (for OpenShift)
-- At least 10GB available storage for model data
+- **Registry Access**: Quay.io or container registry credentials
+- **Storage**: At least 10GB per user for model data
 
 ## 🔧 Key Features
 
-- **Node Selection**: Only schedules on linux/amd64 nodes
+- **Multi-User Support**: Complete isolation per user
+- **CI/CD Pipeline**: Automated build and deployment
+- **GitHub Integration**: Webhook-triggered deployments
 - **Security**: Non-root containers (OpenShift compatible)
 - **Persistence**: Model data persisted across restarts
 - **Health Checks**: Readiness and liveness probes
-- **External Access**: Ingress (K8s) or Route (OpenShift)
+- **External Access**: OpenShift Routes per user

+## 📖 Pipeline Components
 
-For complete documentation including troubleshooting, production considerations, and advanced configuration, see:
-
-- [KUBERNETES.md](../KUBERNETES.md) - Complete deployment guide
+The Tekton pipeline includes:
+1. **Git Clone** - Checkout source code
+2. **Create Namespace** - User-specific namespace creation
+3. **Build Image** - Container image build and push
+4. **Deploy Ollama** - AI model serving deployment
+5. **Deploy Agent** - Main application deployment
+6. **Load Model** - Download and configure AI model
+7. **Create Route** - External access configuration
 
 ## 🆘 Support
 
 If you encounter issues:
-1. Check pod logs: `kubectl logs -f deployment/ci-analysis-agent -n ci-analysis`
-2. Verify node requirements: `kubectl get nodes --show-labels | grep -E "(arch|os)"`
-3. Check the main documentation: [KUBERNETES.md](../KUBERNETES.md) 
+1. Check pipeline logs: `tkn pipelinerun logs --last -f -n ci-analysis-<username>`
+2. Verify deployments: `oc get all -n ci-analysis-<username>`
+3. Check webhook URL: `oc get route ci-analysis-agent-webhook -n ci-analysis-<username>`
+4. See detailed documentation: [tekton/README.md](tekton/README.md)
+
+## 🏗️ Migration from K8s Manifests
+
+The previous manual K8s/OpenShift deployment approach has been replaced with this automated Tekton pipeline approach for better CI/CD integration and multi-user support.
