-Renovate supports upgrading Node.js versions in `.travis.yml` files.
+Renovate can upgrade the [Node.js](https://nodejs.org/en/) runtime used by your project so that you're using the latest bug fixes, performance improvements, security mitigations, etc. that meet your project's unique needs.
+
+## File Support
+
+Renovate is capable of managing the Node.js version in the following files:
+
+* The [`engines`](https://docs.npmjs.com/files/package.json#engines) field in [`package.json`](https://docs.npmjs.com/files/package.json).
+* The [`.nvmrc`](https://github.com/creationix/nvm#nvmrc) file for the [Node Version Manager](https://github.com/creationix/nvm).
+* The [`node_js`](https://docs.travis-ci.com/user/languages/javascript-with-nodejs/#Specifying-Node.js-versions) field in [`.travis.yml`](https://docs.travis-ci.com/user/customizing-the-build/).
 
 ## How It Works
 
-1.  You must enable Node renovation explicitly in your `renovate.json`: `"node": { "enabled": true }`
-2.  Optionally, configure a `supportPolicy` (otherwise, the default is LTS): `"supportPolicy": ["lts_latest", "current"]`
-3.  Renovate will search repositories for a `.travis.yml` in the root directory
-4.  Existing Node.js versions will be extracted from the `node_js` array if it exists
-5.  Renovate will replace this with the correct versions array based on your configured `supportPolicy` (defaults to `"lts"`)
+Node.js renovation in `package.json > engines` and in `.nvmrc` is enabled by default, if your existing version is pinned.
+
+To enable `.travis.yml` renovation, you must:
+
+1.  Enable Travis renovation explicitly by setting the following Renovate configuration: `"travis": { "enabled": true }`
+2.  Optionally, configure a support policy (As documented below).
+
+When Renovate processes your project's repository it will look for the files listed above and submit a single pull request that upgrades all Node.js versions simulteniously.

+Renovate supports a [`supportPolicy`](https://renovateapp.com/docs/configuration-reference/configuration-options#supportpolicy) option that can be passed the following values and associated versions (current as of December 2017):
+
+**Default:** `lts`
 
 | supportPolicy | versions | description                                               |

@@ -31,3 +44,13 @@ Renovate supports the following `supportPolicy` values and associated versions (
 | lts_latest    | 8        | The latest LTS release                                    |
 
 The version numbers associated with each support policy will be updated as new versions of Node.js are released, moved to LTS or maintenance, etc.
+
+For example, to instruct Renovate to upgrade your project to the latest [Long-term Support](https://github.com/nodejs/Release#release-plan) release, you can use the following configuration:
+
+```json
+"supportPolicy": ["lts_latest"]
+```
+
+It's best to define this support policy inside the `node` configuration object so that it is applied to all Node.js-related files.
