-## Usage
+### Usage
 
 Steerer requires two Kubernetes deployments: one for the version you want to upgrade called _primary_ and one for the _canary_.
 Each deployment must have a corresponding ClusterIP service that exposes a port named http or https.
 These services are used as destinations in a Istio virtual service.
