+# Development Guide
+
+This guide provides instructions for local development and testing of the Flipt Helm charts.
+
+## Prerequisites
+
+Before you begin, ensure you have the following tools installed:
+
+- [Docker](https://docs.docker.com/get-docker/)
+- [kubectl](https://kubernetes.io/docs/tasks/tools/)
+- [Helm](https://helm.sh/docs/intro/install/) (v3.0+)
+- [kind](https://kind.sigs.k8s.io/docs/user/quick-start/#installation)
+- [chart-testing (ct)](https://github.com/helm/chart-testing#installation)
+
+## Setting Up Local Development Environment
+
+### 1. Create a kind Cluster
+
+```bash
+# Create a new kind cluster for testing
+kind create cluster --name flipt-dev
+
+# Verify the cluster is running
+kubectl cluster-info --context kind-flipt-dev
+kubectl get nodes
+```
+
+### 2. Clone and Navigate to Repository
+
+```bash
+git clone https://github.com/flipt-io/helm-charts.git
+cd helm-charts
+```
+
+## Testing Charts Locally
+
+### Testing Flipt v1 Chart
+
+```bash
+# Install Flipt v1 chart
+helm install flipt-v1-test ./charts/flipt
+
+# Check deployment status
+kubectl get pods -l app.kubernetes.io/name=flipt
+kubectl get svc -l app.kubernetes.io/name=flipt
+
+# View logs
+kubectl logs -l app.kubernetes.io/name=flipt
+
+# Port forward to access Flipt UI
+kubectl port-forward svc/flipt-v1-test 8080:8080
+
+# Visit http://localhost:8080 in your browser
+```
+
+### Testing Flipt v2 Chart
+
+```bash
+# Install Flipt v2 chart
+helm install flipt-v2-test ./charts/flipt-v2
+
+# Check deployment status
+kubectl get pods -l app.kubernetes.io/name=flipt-v2
+kubectl get svc -l app.kubernetes.io/name=flipt-v2
+
+# View logs
+kubectl logs -l app.kubernetes.io/name=flipt-v2
+
+# Port forward to access Flipt UI
+kubectl port-forward svc/flipt-v2-test 8080:8080
+
+# Visit http://localhost:8080 in your browser
+```
+
+## Testing with Custom Values
+
+### Create Test Values Files
+
+Create custom values files for testing different configurations:
+
+```bash
+# Create test values for v1
+cat > test-values-v1.yaml << EOF
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: flipt-v1.local
+      paths:
+        - path: /
+          pathType: Prefix
+
+flipt:
+  config:
+    log:
+      level: DEBUG
+    db:
+      url: "file:/var/opt/flipt/flipt.db"
+EOF
+
+# Create test values for v2
+cat > test-values-v2.yaml << EOF
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: flipt-v2.local
+      paths:
+        - path: /
+          pathType: Prefix
+
+flipt:
+  config:
+    log:
+      level: DEBUG
+    storage:
+      type: local
+      local:
+        path: /var/opt/flipt
+EOF
+```
+
+### Install with Custom Values
+
+```bash
+# Install v1 with custom values
+helm install flipt-v1-custom ./charts/flipt -f test-values-v1.yaml
+
+# Install v2 with custom values
+helm install flipt-v2-custom ./charts/flipt-v2 -f test-values-v2.yaml
+```
+
+## Development Workflow
+
+### 1. Template Testing (Dry Run)
+
+Before installing, always test your templates:
+
+```bash
+# Test v1 chart templates
+helm template flipt-v1-test ./charts/flipt
+
+# Test v2 chart templates
+helm template flipt-v2-test ./charts/flipt-v2
+
+# Test with custom values
+helm template flipt-v1-test ./charts/flipt -f test-values-v1.yaml
+helm template flipt-v2-test ./charts/flipt-v2 -f test-values-v2.yaml
+
+# Save templates to files for inspection
+helm template flipt-v1-test ./charts/flipt > v1-templates.yaml
+helm template flipt-v2-test ./charts/flipt-v2 > v2-templates.yaml
+```
+
+### 2. Chart Linting
+
+```bash
+# Lint all charts
+ct lint --lint-conf lintconf.yaml --target-branch main
+
+# Lint specific chart
+ct lint --lint-conf lintconf.yaml --charts charts/flipt
+ct lint --lint-conf lintconf.yaml --charts charts/flipt-v2
+
+# YAML linting
+yamllint -c lintconf.yaml charts/
+
+# Helm linting
+helm lint charts/flipt
+helm lint charts/flipt-v2
+```
+
+### 3. Upgrade Testing
+
+```bash
+# Test upgrades for v1
+helm upgrade flipt-v1-test ./charts/flipt
+helm upgrade flipt-v1-test ./charts/flipt -f test-values-v1.yaml
+
+# Test upgrades for v2
+helm upgrade flipt-v2-test ./charts/flipt-v2
+helm upgrade flipt-v2-test ./charts/flipt-v2 -f test-values-v2.yaml
+```
+
+### 4. Chart Testing with ct
+
+```bash
+# Run comprehensive chart tests
+ct install --config ct.yaml
+
+# Test specific charts
+ct install --config ct.yaml --charts charts/flipt
+ct install --config ct.yaml --charts charts/flipt-v2
+```
+
+## Debugging Common Issues
+
+### Pod Not Starting
+
+```bash
+# Check pod status
+kubectl get pods -l app.kubernetes.io/instance=<release-name>
+
+# Describe pod for detailed information
+kubectl describe pod -l app.kubernetes.io/instance=<release-name>
+
+# Check logs
+kubectl logs -l app.kubernetes.io/instance=<release-name>
+
+# Check events
+kubectl get events --sort-by=.metadata.creationTimestamp
+```
+
+### Configuration Issues
+
+```bash
+# Check ConfigMap contents
+kubectl get configmap <release-name> -o yaml
+
+# Check rendered templates
+helm get manifest <release-name>
+
+# Check values used
+helm get values <release-name>
+```
+
+### Network Issues
+
+```bash
+# Check services
+kubectl get svc -l app.kubernetes.io/instance=<release-name>
+
+# Check endpoints
+kubectl get endpoints <release-name>
+
+# Test connectivity
+kubectl run -it --rm debug --image=busybox --restart=Never -- sh
+# Inside the pod: wget -qO- http://<service-name>:8080/health
+```
+
+## Making Changes
+
+### 1. Modify Chart Files
+
+Make your changes to:
+- `charts/flipt/` (for v1 changes)
+- `charts/flipt-v2/` (for v2 changes)
+
+### 2. Test Changes
+
+```bash
+# Lint changes
+ct lint --lint-conf lintconf.yaml --target-branch main
+
+# Template test
+helm template test-release ./charts/flipt
+helm template test-release ./charts/flipt-v2
+
+# Install test
+helm install test-release ./charts/flipt
+helm install test-release ./charts/flipt-v2
+```
+
+### 3. Clean Up Test Releases
+
+```bash
+# List releases
+helm list
+
+# Uninstall test releases
+helm uninstall flipt-v1-test
+helm uninstall flipt-v2-test
+helm uninstall flipt-v1-custom
+helm uninstall flipt-v2-custom
+```
+
+## Environment Cleanup
+
+### Clean Up Kubernetes Resources
+
+```bash
+# Delete all test releases
+helm list --short | xargs -I {} helm uninstall {}
+
+# Verify cleanup
+kubectl get all
+```
+
+### Delete kind Cluster
+
+```bash
+# Delete the development cluster
+kind delete cluster --name flipt-dev
+
+# Verify deletion
+kind get clusters
+```
+
+## Tips and Best Practices
+
+### 1. Use Separate Namespaces
+
+```bash
+# Create namespace for testing
+kubectl create namespace flipt-test
+
+# Install charts in specific namespace
+helm install flipt-v1 ./charts/flipt -n flipt-test
+helm install flipt-v2 ./charts/flipt-v2 -n flipt-test
+
+# Clean up namespace
+kubectl delete namespace flipt-test
+```
+
+### 2. Monitor Resource Usage
+
+```bash
+# Check resource usage
+kubectl top nodes
+kubectl top pods
+
+# Check resource requests/limits
+kubectl describe deployment <release-name>
+```
+
+### 3. Test Different Scenarios
+
+- Test with minimal values (defaults)
+- Test with custom configurations
+- Test upgrades between versions
+- Test with different Kubernetes versions
+- Test resource limits and requests
+- Test ingress configurations
+- Test persistent storage
+
+### 4. Version Testing
+
+```bash
+# Test with specific image versions
+helm install flipt-v1 ./charts/flipt --set image.tag=v1.59.0
+helm install flipt-v2 ./charts/flipt-v2 --set image.tag=v2-beta
+```
+
+## Continuous Integration
+
+The repository uses GitHub Actions for automated testing. You can run similar tests locally:
+
+```bash
+# Run the same linting as CI
+ct lint --lint-conf lintconf.yaml --target-branch main
+
+# Run the same installation tests as CI
+ct install --config ct.yaml
+```
+
+For more information about the CI pipeline, see the GitHub Actions workflows in `.github/workflows/`.
