+# Node.js Role Example
+
+This example is an extension of the [Node.js example](../nodejs/README.md). Please read through the directions in that example's README to get this example running locally through Vagrant.
+
+The primary difference in this example (as explained in [Ansible for DevOps](https://www.ansiblefordevops.com/)) is that the actual _installation of Node.js_ is done in a new `nodejs` role.
+
+After running `vagrant up`, perform the following steps to access the app via a hostname:
+
+ 1. [Edit your hosts file](http://www.rackspace.com/knowledge_center/article/how-do-i-modify-my-hosts-file), adding the line `192.168.55.56 nodejs-role.dev` so you can connect to the VM.
+ 2. Open your browser and access [http://nodejs-role.dev/](http://nodejs-role.dev/).
