 # sandbox-operator
-A kubernetes operator for creating isolated environments
+
+## Introduction
+
+This is a sandbox operator that creates segregated namespaces and sets up RBAC for authenticated users specified in the CRD.
+
+## Local Testing
+
+Run `make test-unit` to run the operator unit tests
+
+Run `make test-integration` to deploy the operator to a Kind cluster and verify the operator pod enters a running state.
+
+Iterative deployments can be made with `make deploy`. This will rebuild the operator and deploy to it to an existing cluster.
+
+To test with a different version of Kubernetes, pass in `KUBERNETES_VERSION` to the `make` command (e.g. `make test-integration KUBERNETES_VERSION=v1.17.0`)
