+# Contribution guide
+
+## Update chart dependencies
+
+Add Bitnami Helm repository:
+
+```bash
+helm repo add bitnami https://charts.bitnami.com/bitnami
+helm repo update
+```
+
+Look for existing versions:
+
+```bash
+helm search repo -l mongodb --versions
+```
+
+Manually edit `Chart.yaml` with the version.
+
+Update `Chart.lock`:
+
+```bash
+helm dependency update
+```
+
+## Validate on a test cluster
+
+Create a `values.mine.yaml` file:
+
+```yaml
+dotnet:
+  environment: Development
+  enableOpenTelemetry: false
+webapp:
+  db:
+    connectionString: mongodb://root:admin@todoblazor-mongodb:27017/todolist?authSource=admin
+    databaseName: todolist
+ingress:
+  enabled: true
+  className: traefik
+  annotations:
+    cert-manager.io/cluster-issuer: letsencrypt-prod
+mongodb:
+  enabled: true
+  auth:
+    rootPassword: admin
+```
+
+Install or update the application:
+
+```bash
+helm upgrade --install todoblazor . \
+  -f values.yaml -f values.mine.yaml \
+  --set webapp.host=todoblazor.console.$SANDBOX_ID.instruqt.io \
+  --namespace demo --create-namespace
+```
+
+Check everything is ok in the namespace:
+
+```bash
+kubectl get pod,svc,deploy,rs,ingress,secret,pvc -n demo
+```
+
+Open the web application in a browser:
+
+```bash
+echo https://todoblazor.console.$SANDBOX_ID.instruqt.io/swagger
+```
+
+If needed, debug with:
+
+- Forward MongoDB port to view the database from Compass (with connection string "mongodb://root:admin@localhost:27017/todolist?authSource=admin")
+
+    ```bash
+    kubectl port-forward svc/todoblazor-mongodb -n demo 27017:27017
+    ```
+
+- Have a shell in a MongoDB container
+
+  ```bash
+  kubectl exec -it deploy/todoblazor-mongodb -n demo -- bash
+  ```
+
+At the end, clean everything:
+
+```bash
+helm delete todoblazor -n demo
+kubectl delete ns demo
+```
