 ## Enabling Tracing
 
-Enabling tracing requires two pieces of configuration. The first is a resource called `NginxProxy`, which contains global settings relating to the NGINX data plane. This resource is created and managed by the [cluster operator](https://gateway-api.sigs.k8s.io/concepts/roles-and-personas/), and is referenced in the `parametersRef` field of the GatewayClass. This resource can be created and linked when we install NGINX Gateway Fabric using its helm chart, or it can be added later. In this guide we will install the resource using the helm chart, but will also show what it looks like in case you want to add it after installation.

 The `NginxProxy` resource contains configuration for the collector, and applies to all Gateways and routes under the GatewayClass. It does not enable tracing, but is a prerequisite to the next piece of configuration.
 
-The second piece of configuration is the `ObservabilityPolicy`, which is a [Policy](https://gateway-api.sigs.k8s.io/reference/policy-attachment/) that targets HTTPRoutes or GRPCRoutes. This Policy is created by the [application developer](https://gateway-api.sigs.k8s.io/concepts/roles-and-personas/) and enables tracing for a specific route or routes. It requires the `NginxProxy` resource to exist in order to complete the tracing configuration.
