+    **A cloud native Kubernetes Global Balancer**
+
+    A Global Service Load Balancing solution with a focus on having cloud native qualities and work natively in a Kubernetes context.
+
+    Key Differentiators:
+     - Load balancing is based on timeproof DNS protocol which is perfect for global scope and extremely reliable
+     - No dedicated management cluster and no single point of failure
+     - Kubernetes native application health checks utilizing status of Liveness and Readiness probes for load balancing decisions
+     - Configuration with a single Kubernetes CRD of `Gslb` kind
+
+    Operator needs to be configured by setting couple of environment variables. This can be done by modifying
+    the subscription yaml in the web ui or via kubectl. Here is an example of changing the `EDGE_DNS_ZONE`:
+
+    ```yaml
+    kind: Subscription
+      ...
+    spec:
+      ...
+      config:
+        env:
+        - name: CLUSTER_GEO_TAG
+          value: us
+        - name: EDGE_DNS_ZONE
+          value: mycloud.example.com
+          ...
+     ```
+     For more deployment variables see [helm code](https://github.com/k8gb-io/k8gb/blob/5beb6fc5244ef61c77fcbebb5243908ee77c615f/chart/k8gb/templates/operator.yaml#L53:L70).
