+
+### New feature: ResourceDistribution
+
+For the scenario, where the namespace-scoped resources such as Secret and ConfigMap need to be distributed or synchronized to different namespaces,
+the native k8s currently only supports manual distribution and synchronization by users one-by-one, which is very inconvenient.
+
+Therefore, in the face of these scenarios that require the resource distribution and **continuously synchronization across namespaces**, we provide a tool, namely **ResourceDistribution**, to do this automatically.
+
+Currently, ResourceDistribution supports the two kind resources --- **Secret & ConfigMap**.
