 `gulp-sass` must be used in a Gulp task. Your task can call `sass()` (to asynchronously render your CSS), or `sass.sync()` (to synchronously render your CSS). Then, export your task with the `export` keyword. We'll show some examples of how to do that.
 
-**⚠️ Note:** When using Dart Sass, **synchronous rendering is twice as fast as asynchronous rendering**. The Sass team is exploring ways to improve asynchronous rendering with Dart Sass, but for now you will get the best performance from `sass.sync()`. If performance is critical, you can use `node-sass` instead, but bear in mind that `node-sass` may not support modern Sass features you rely on.
