 # A Prometheus & Grafana docker-compose stack
 Here's a quick start to stand-up a [Prometheus](http://prometheus.io/) stack containing Prometheus, Grafana and Node scraper to monitor your Docker infrastructure. A big shoutout to [philicious](https://github.com/philicious) for kicking this project off!
 
-##Pre-requisites
+## 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 & Configuration
 Clone the project locally to your Docker host. 
 
 If you would like to change which targets should be monitored or make configuration changes edit the [/prometheus/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.

 ### Test Alerts
 A quick test for your alerts is to stop a service. Stop the node_exporter container and you should notice shortly the alert arrive in Slack. Also check the alerts in both the Alert Manager and Prometheus Alerts just to understand how they flow through the system.
