+
+## Development Setup
+
+1. **Clone the repository**
+   ```bash
+   git clone https://github.com/your-username/k8s-game-2048.git
+   cd k8s-game-2048
+   ```
+
+2. **Local Development**
+   ```bash
+   # Start local development server
+   npm start
+   # Or with Python
+   python3 -m http.server 8080 --directory src
+   ```
+
+3. **Build Docker Image**
+   ```bash
+   npm run build
+   # Or
+   docker build -t k8s-game-2048 .
+   ```
+
+## Git Workflow
+
+We use a GitFlow-inspired workflow:
+
+- **`master`** - Production-ready code, deployed to production automatically
+- **`staging`** - Staging branch, deployed to staging environment automatically
+- **`develop`** - Development branch, deployed to dev environment automatically  
+- **`feature/*`** - Feature branches, create PR to develop
+- **`hotfix/*`** - Hotfix branches, create PR to master
+- **`release/*`** - Release branches for production deployment
+
+### Branch Protection Rules
+
+- **`master`**: Requires PR review, all checks must pass
+- **`staging`**: Requires PR review, all checks must pass
+- **`develop`**: Requires PR review, all checks must pass
+
+## Deployment Environments
+
+| Environment | Branch | Domain | Auto-Deploy |
+|-------------|--------|---------|------------|
+| Development | `develop` | `2048-dev.wa.darknex.us` | ✅ |
+| Staging | `staging` | `2048-staging.wa.darknex.us` | ✅ |
+| Production | `master` | `2048.wa.darknex.us` | ✅ |
+
+## Making Changes
+
+### For New Features
+
+1. Create a feature branch from `develop`:

+   git pull origin develop
+   git checkout -b feature/your-feature-name
+   ```
+
+2. Make your changes and commit:
+   ```bash
+   git add .
+   git commit -m "feat: add your feature description"
+   ```
+
+3. Push and create a PR to `develop`:

+   ```
+
+### For Bug Fixes
+
+1. Create a hotfix branch from `master`:
+   ```bash
+   git checkout master
+   git pull origin master
+   git checkout -b hotfix/fix-description
+   ```
+
+2. Make your changes and create PR to `master`
+

+```
+
+## Code Style
+
+- Use 2 spaces for indentation
+- Use meaningful variable and function names
+- Add comments for complex logic
+- Keep functions small and focused
+
+## Pull Request Process

+# Knative & Kourier Setup Guide
+
+This guide will help you set up Knative Serving with Kourier networking layer on your Kubernetes cluster.
+
+## Prerequisites
+
+- Kubernetes cluster (v1.21+)
+- kubectl configured and working
+- Cluster admin permissions
+- LoadBalancer support (cloud provider or MetalLB)
+
+## Quick Setup
+
+Run the provided scripts in order:
+
+```bash
+# 1. Install Knative Serving
+./scripts/setup-knative.sh
+
+# 2. Install Kourier networking layer
+./scripts/setup-kourier.sh
+```
+
+## Manual Setup
+
+If you prefer to install manually:
+
+### 1. Install Knative Serving
+
+```bash
+# Install CRDs
+kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.12.0/serving-crds.yaml
+
+# Install core components
+kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.12.0/serving-core.yaml
+
+# Install HPA autoscaler
+kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.12.0/serving-hpa.yaml
+```
+
+### 2. Install Kourier
+
+```bash
+# Install Kourier
+kubectl apply -f https://github.com/knative/net-kourier/releases/download/knative-v1.12.0/kourier.yaml
+
+# Configure Knative to use Kourier
+kubectl patch configmap/config-network \
+  --namespace knative-serving \
+  --type merge \
+  --patch '{"data":{"ingress-class":"kourier.ingress.networking.knative.dev"}}'
+```
+
+### 3. Configure Domain
+
+```bash
+# Set your custom domain
+kubectl patch configmap/config-domain \
+  --namespace knative-serving \
+  --type merge \
+  --patch '{"data":{"wa.darknex.us":""}}'
+```
+
+### 4. Set up TLS (Optional but Recommended)
+
+```bash
+# Install cert-manager
+kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.13.0/cert-manager.yaml
+
+# Install Knative cert-manager integration
+kubectl apply -f https://github.com/knative/net-certmanager/releases/download/knative-v1.12.0/release.yaml
+
+# Create Let's Encrypt ClusterIssuer
+kubectl apply -f - <<EOF
+apiVersion: cert-manager.io/v1
+kind: ClusterIssuer
+metadata:
+  name: letsencrypt-prod
+spec:
+  acme:
+    server: https://acme-v02.api.letsencrypt.org/directory
+    email: admin@darknex.us
+    privateKeySecretRef:
+      name: letsencrypt-prod
+    solvers:
+    - http01:
+        ingress:
+          class: kourier.ingress.networking.knative.dev
+EOF
+
+# Configure Knative to use cert-manager
+kubectl patch configmap/config-certmanager \
+  --namespace knative-serving \
+  --type merge \
+  --patch '{"data":{"issuerRef":"kind: ClusterIssuer\nname: letsencrypt-prod"}}'
+
+# Enable auto-TLS
+kubectl patch configmap/config-network \
+  --namespace knative-serving \
+  --type merge \
+  --patch '{"data":{"autoTLS":"Enabled","httpProtocol":"Redirected"}}'
+```
+
+## DNS Configuration
+
+After installation, configure your DNS to point to the Kourier LoadBalancer:
+
+1. **Get the LoadBalancer IP**:
+   ```bash
+   kubectl get svc kourier -n kourier-system
+   ```
+
+2. **Create DNS records**:
+   ```
+   2048-dev.wa.darknex.us      -> LoadBalancer IP
+   2048-staging.wa.darknex.us  -> LoadBalancer IP
+   2048.wa.darknex.us          -> LoadBalancer IP
+   *.wa.darknex.us             -> LoadBalancer IP (wildcard)
+   ```
+
+## Verification
+
+Test your setup:
+
+```bash
+# Check Knative Serving
+kubectl get pods -n knative-serving
+
+# Check Kourier
+kubectl get pods -n kourier-system
+
+# Check cert-manager (if installed)
+kubectl get pods -n cert-manager
+
+# Deploy a test service
+kubectl apply -f manifests/dev/
+
+# Check service status
+kubectl get ksvc -n game-2048-dev
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Pods stuck in Pending**:
+   - Check node resources: `kubectl describe nodes`
+   - Check PVC status: `kubectl get pvc -A`
+
+2. **LoadBalancer IP not assigned**:
+   - Ensure your cluster supports LoadBalancer services
+   - For local clusters, consider using MetalLB
+
+3. **TLS certificates not issued**:
+   - Check cert-manager logs: `kubectl logs -n cert-manager -l app=cert-manager`
+   - Verify DNS propagation: `dig 2048-dev.wa.darknex.us`
+
+4. **Service not accessible**:
+   - Check Kourier gateway logs: `kubectl logs -n kourier-system -l app=3scale-kourier-gateway`
+   - Verify domain mapping: `kubectl get domainmapping -A`
+
+### Useful Commands
+
+```bash
+# Check Knative service status
+kubectl get ksvc -A
+
+# Check revisions
+kubectl get rev -A
+
+# Check domain mappings
+kubectl get domainmapping -A
+
+# Check Kourier configuration
+kubectl get svc kourier -n kourier-system -o yaml
+
+# Check Knative configuration
+kubectl get cm -n knative-serving
+
+# Debug service logs
+kubectl logs -n <namespace> -l serving.knative.dev/service=<service-name>
+```
+
+## Advanced Configuration
+
+### Custom Autoscaling
+
+```yaml
+# Add to service annotations
+autoscaling.knative.dev/minScale: "0"
+autoscaling.knative.dev/maxScale: "100"
+autoscaling.knative.dev/target: "70"
+autoscaling.knative.dev/scaleDownDelay: "30s"
+autoscaling.knative.dev/window: "60s"
+```
+
+### Traffic Splitting
+
+```yaml
+# In Knative Service spec
+traffic:
+- percent: 90
+  revisionName: myapp-00001
+- percent: 10
+  revisionName: myapp-00002
+```
+
+### Custom Resource Limits
+
+```yaml
+# In container spec
+resources:
+  requests:
+    cpu: 100m
+    memory: 128Mi
+  limits:
+    cpu: 1000m
+    memory: 512Mi
+```
+
+## Monitoring
+
+Consider installing these additional tools:
+
+- **Knative Monitoring**: `kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.12.0/monitoring.yaml`
+- **Prometheus**: For metrics collection
+- **Grafana**: For visualization
+- **Jaeger**: For distributed tracing
+
+## Next Steps
+
+1. Deploy the 2048 game: `kubectl apply -f manifests/dev/`
+2. Set up monitoring and alerting
+3. Configure backup and disaster recovery
+4. Implement proper RBAC policies
+5. Set up GitOps with ArgoCD or Flux
