 ## Overview
 
-
 NGINX Gateway Fabric metrics are displayed in [Prometheus](https://prometheus.io/) format. These metrics are served through a metrics server orchestrated by the controller-runtime package on HTTP port `9113`. When installed, Prometheus automatically scrapes this port and collects metrics. [Grafana](https://grafana.com/) can be used for rich visualization of these metrics.

+## Overview

 In this guide we will configure advanced routing rules for multiple applications. These rules will showcase request matching by path, headers, query parameters, and method. For an introduction to exposing your application, we recommend that you follow the [basic guide]({{< relref "/how-to/traffic-management/routing-traffic-to-your-app.md" >}}) first.
 
 The following image shows the traffic flow that we will be creating with these rules.

 The goal is to create a set of rules that will result in client requests being sent to specific backends based on the request attributes. In this diagram, we have two versions of the `coffee` service. Traffic for v1 needs to be directed to the old application, while traffic for v2 needs to be directed towards the new application. We also have two `tea` services, one that handles GET operations and one that handles POST operations. Both the `tea` and `coffee` applications share the same Gateway.

+## Overview
+
 Securing client server communication is a crucial part of modern application architectures. One of the most important steps in this process is implementing HTTPS (HTTP over TLS/SSL) for all communications. This encrypts the data transmitted between the client and server, preventing eavesdropping and tampering. To do this, you need an SSL/TLS certificate from a trusted Certificate Authority (CA). However, issuing and managing certificates can be a complicated manual process. Luckily, there are many services and tools available to simplify and automate certificate issuance and management.

 - Use [Let’s Encrypt](https://letsencrypt.org) as the Certificate Authority (CA) issuing the TLS certificate.
 - Use [cert-manager](https://cert-manager.io) to automate the provisioning and management of the certificate.
 
-## Prerequisities
+## Before you begin
 
 - Administrator access to a Kubernetes cluster.
 - [Helm](https://helm.sh) and [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl) must be installed locally.
 - [NGINX Gateway Fabric deployed]({{< relref "/installation/" >}}) in the Kubernetes cluster.
 - A DNS-resolvable domain name is required. It must resolve to the public endpoint of the NGINX Gateway Fabric deployment, and this public endpoint must be an external IP address or alias accessible over the internet. The process here will depend on your DNS provider. This DNS name will need to be resolvable from the Let’s Encrypt servers, which may require that you wait for the record to propagate before it will work.
