 ### Node.js
 
-#### Installation
-
-On Node, Resemble uses the `canvas` package instead of the native canvas support in the browser. To prevent browser users from being forced into installing Canvas, it's included as a peer dependency which means you have to install it alongside Resemble.
-
-Canvas relies on some native image manipulation libraries to be install on the system. Please read the [Canvas installation instructions](https://www.npmjs.com/package/canvas) for OSX/Windows/Linux.

-*Example commands for installation on OSX*
-
-``` bash
-npm install resemblejs
-brew install pkg-config cairo libpng jpeg giflib
-npm install canvas
-```
