-###Auto reload & CSS injecting
 Streams are now supported in BrowserSync, so you can call `reload` when all your tasks are complete & all browsers will be informed of the changes.

 **SASS & Source Maps**
 
 If you use [gulp-ruby-sass](https://www.npmjs.org/package/gulp-ruby-sass) with `sourcemap: true` option `*.css.map` file/files will be generated and after css injection browser will be reloaded. To prevent refreshing page after css injection use [gulp-filter](https://www.npmjs.org/package/gulp-filter) package.
 
 For example:

 **Browser Reloading**
 
 Sometimes you might just want to reload the page completely (for example, after processing a bunch of JS files) - you can do that
 by passing `once` as an option. This will stop `reload` being call multiple times.
