 ##Pre-requisites
 Before we get started installing the Prometheus stack. Ensure you install the latest version of docker and [docker-compose](https://docs.docker.com/compose/install/) on your Docker host machine. This has also been tested with Docker for Mac and it works well.
 
-##Installation & Configuration
+##Installation
 Clone the project to your Docker host. 
 
 If you would like to change which targets should be monitored or make configuration changes edit the [/prom/prometheus.yml](https://github.com/vegasbrianc/prometheus/blob/version-2/prometheus/prometheus.yml) file. The targets section is where you define what should be monitored by Prometheus. The names defined in this file are actually sourced from the service name in the docker-compose file. If you wish to change names of the services you can add the "container_name" parameter in the `docker-compose.yml` file. 
 
+## Configuration
+In order to pull GitHub stats consistently it is recommended you create a personal access token inside of GitHub. This token will allow you to query the GitHub API more frequently than a public user. [Create GitHub Token](https://github.com/settings/tokens). Copy the GitHub Token you created and paste into the bottom of [docker-compose.yml](https://github.com/vegasbrianc/github-monitoring/blob/master/docker-compose.yml) file under the metrics service section.
