+# incubator/raw
+
+The `incubator/raw` chart takes a list of raw Kubernetes resources and
+merges each resource with a default `metadata.labels` map and installs
+the result.
+
+Some use cases for this chart include Helm-based installation and
+maintenance of resources of kinds:
+- LimitRange
+- PriorityClass
+
+## Usage
+
+### STEP 1: Create a yaml file containing your raw resources.
+
+```
+# raw-priority-classes.yaml
+
+resources:
+
+  - apiVersion: scheduling.k8s.io/v1beta1
