+## Extra objects
+You can add extra objects to the deployment, like configmaps, secrets, etc. by adding them to the `extraObjects` section in the `values.yaml` file so no additional deployment/pipeline is needed.
+
+```yaml
+# values.yaml
+extraObjects:
+  - apiVersion: v1
+    kind: ConfigMap
+    metadata:
+      name: "extra"
+    data:
+      something: "extra"
+  - |
+    apiVersion: v1
+    kind: ConfigMap
+    metadata:
+      name: "templated"
+    data:
+      something: {{ printf "templated" }}
+```
