+Node.js is used for many different purposes, but with Drupal, it is most often used as part of a toolset for Front End development or certain CI tasks.
+
+Drupal VM includes built-in support for Node.js—all you need to do is make sure `nodejs` is listed in the list of `installed_extras` inside `config.yml` before your provision Drupal VM.
+
+## Choosing a version of Node.js
+
+You can choose a version of Node.js to install using the `nodejs_version` variable in `config.yml`. See the `geerlingguy.nodejs` role documentation for all the currently-available versions for your OS.
+
+```yaml
+nodejs_version: "0.12"
+```
+
+## Installing global packages via NPM
+
+To install packages globally, you can add them to the list of `nodejs_npm_global_packages` in `config.yml`. As an example, many developers use `phantomjs` as a ghost web driver for Behat tests inside Drupal VM. To install it globally, add it to the list:
+
+```yaml
+nodejs_npm_global_packages:
+  - name: phantomjs
+```
