+# Installing and Configuring the Metering Operator
+
+For the next steps, you will need access to an OpenShift cluster (4.3 or newer).
+
+1. In OpenShift, create a namespace called `openshift-metering` if one does not exist, and label the namespace with `openshift.io/cluster-monitoring=true`.
+
+2. Install the Metering Operator in the `openshift-metering` namespace, using the OpenShift web console (search for Metering in OperatorHub).
+
+3. Create a key/value secret in the `openshift-metering` namespace called `metering-aws` where the keys are `aws-access-key-id` and `aws-secret-access-key` with your associated aws secret values.
+
+4. Create a Metering Configuration that points to your bucket/path/ and region, and references the aws secret that you created above. It should look similar to the following:
+
+```
+apiVersion: metering.openshift.io/v1
+kind: MeteringConfig
+metadata:
+  name: operator-metering
+  namespace: openshift-metering
+spec:
+  storage:
+    hive:
+      s3:
+        bucket: your-bucketname/path/
+        createBucket: false
+        region: us-east-1
+        secretName: metering-aws
+      type: s3
+    type: hive
+```
+
+To check that Metering has been configured correctly, you can view & ensure that all of the pods are running & ready.
