+Starting with `1.0.0`, the sass-loader requires [node-sass](https://github.com/sass/node-sass) as [`peerDependency`](https://docs.npmjs.com/files/package.json#peerdependencies). Thus you are able to specify the required version accurately.

+### Imports
+
+webpack provides an [advanced mechanism to resolve files](http://webpack.github.io/docs/resolving.html). The sass-loader uses node-sass' custom importer feature to pass all queries to the webpack resolving engine. Thus you can import your sass-modules from `node_modules`. Just prepend them with a `~` which tells webpack to look-up the [`modulesDirectories`](http://webpack.github.io/docs/configuration.html#resolve-modulesdirectories)
+
+```css
+@import "~bootstrap/less/bootstrap";
+```
+
+It's important to only prepend it with `~`, because `~/` resolves to the home-directory. webpack needs to distinguish between `bootstrap` and `~bootstrap` because CSS- and Sass-files have no special syntax for importing relative files. Writing `@import "file"` is the same as `@import "./file";`

 ## Source maps
 
-Because of browser limitations, source maps are only available in conjunction with the [extract-text-webpack-plugin](https://github.com/webpack/extract-text-webpack-plugin). Use that plugin to extract the CSS code from the generated JS bundle into a separate file (which even improves the perceived performance because JS and CSS are loaded in parallel).

-## Caveats
-
-Currently the sass-loader does not follow all of the webpack loader guidelines. The general problem is that the entry scss-file is passed to [node-sass](https://github.com/sass/node-sass) which does pretty much the rest. Thus `@import` statements inside your scss-files cannot be resolved by webpack's resolver. However, there is an [issue for that missing feature in libsass](https://github.com/sass/libsass/issues/21).
