 - `includePaths`: an array of include paths
+- `onlyIncluded`: true/false whether to use only what is in app/styles and includePaths. Helps with performance when using NPM linked modules
 - `sourceMap`: controls whether to generate sourceMaps, defaults to `true` in development. The sourceMap file will be saved to `options.outputFile + '.map'`
 - `extension`: specifies the file extension for the input files, defaults to `scss`. Set to `sass` if you want to use `.sass` instead.
 - `nodeSass`: Allows a different version of [node-sass](https://www.npmjs.com/package/node-sass) to be used (see below)
