Continue loading Node Sass by default
This documents the option to use Dart Sass, and encourages users to explicitly choose their implementation, but it doesn't change the existing behavior.master

# Contributing to Gulp Sass
|

|

`gulp-sass` is a very light-weight wrapper around either [Dart Sass][] or [Node Sass][] (which in turn is a Node binding for [LibSass][]. All of these are implementations of the [Sass][] language.

||||

||||

Gulp Sass is a very light-weight [Gulp](https://github.com/gulpjs/gulp) wrapper for [`node-sass`](https://github.com/sass/node-sass), which in turn is a Node binding for [`libsass`](https://github.com/sass/libsass), which in turn is a port of [`Sass`](https://github.com/sass/sass).

## Submitting Issues

||||
* Before creating a new issue, perform a [cursory search](https://github.com/issues?utf8=%E2%9C%93&q=repo%3Adlmanning%2Fgulp-sass+repo%3Asass%2Fdart-sass+repo%3Asass%2Fnode-sass+repo%3Asass%2Flibsass+repo%3Asass%2Fsass+repo%3Asass-eyeglass%2Feyeglass) in the Gulp Sass, Dart Sass, Node Sass, Libsass, and main Sass repos to see if a similar issue has already been submitted. Please also refer to our [Common Issues and Their Fixes](https://github.com/dlmanning/gulp-sass/wiki/Common-Issues-and-Their-Fixes) page for some basic troubleshooting.

|
||||
* Issue titles should be descriptive, explaining at the high level what it is about.
|
||||
* Please include the version of `gulp-sass`, Node, and NPM you are using, as well as what operating system you are having a problem on.

You can choose whether to use [Dart Sass][] or [Node Sass][] by setting the `sass.compiler` property. Node Sass will be used by default, but it's strongly recommended that you set it explicitly for forwards-compatibility in case the default ever changes.

Note that when using Dart Sass, **synchronous compilation is twice as fast as asynchronous compilation** by default, due to the overhead of asynchronous callbacks. To avoid this overhead, you can use the [`fibers`](https://www.npmjs.com/package/fibers) package to call asynchronous importers from the synchronous code path. To enable this, pass the `Fiber` class to the `fiber` option:

## Options
|
||||
|

`gulp-sass` supports both [Dart Sass][] and [Node Sass][]. You choose which one to use by writing either `require('gulp-sass')(require('sass'))` for Dart Sass or `require('gulp-sass')(require('node-sass'))` for Node Sass. One or the other must be passed in.

[Node Sass]: https://github.com/sass/node-sass

Pass in options just like you would for [Node Sass](https://github.com/sass/node-sass#options); they will be passed along just as if you were using Node Sass. Except for the `data` option which is used by gulp-sass internally. Using the `file` option is also unsupported and results in undefined behaviour that may change without notice.
