 Vue CLI projects comes with support for [PostCSS](http://postcss.org/), [CSS Modules](https://github.com/css-modules/css-modules) and pre-processors including [Sass](https://sass-lang.com/), [Less](http://lesscss.org/) and [Stylus](http://stylus-lang.com/).
 
+## Referencing Assets
+
+All compiled CSS are processed by [css-loader](https://github.com/webpack-contrib/css-loader), which parses `url()` and resolves them as module requests. This means you can refer to assets using relative paths based on the local file structure. Note if you want to reference a file inside an npm dependency or via webpack alias, the path must be prefixed with `~` to avoid ambiguity. See [Static Asset Handling](./html-and-static-assets.md#static-assets-handling) for more details.
+
 ## Pre-Processors
 
 You can select pre-processors (Sass/Less/Stylus) when creating the project. If you did not do so, the internal webpack config is still pre-configured to handle all of them. You just need to manually install the corresponding webpack loaders:

 Vue CLI 项目天生支持 [PostCSS](http://postcss.org/)、[CSS Modules](https://github.com/css-modules/css-modules) 和包含 [Sass](https://sass-lang.com/)、[Less](http://lesscss.org/)、[Stylus](http://stylus-lang.com/) 在内的预处理器。
 
+## 引用静态资源
+
+所有编译后的 CSS 都会通过 [css-loader](https://github.com/webpack-contrib/css-loader) 来解析其中的 `url()` 引用，并将这些引用作为模块请求来处理。这意味着你可以根据本地的文件结构用相对路径来引用静态资源。另外要注意的是如果你想要引用一个 npm 依赖中的文件，或是想要用 webpack alias，则需要在路径前加上 `~` 的前缀来避免歧义。更多细节请参考[处理静态资源](./html-and-static-assets.md#处理静态资源)。
+
 ## 预处理器
 
 你可以在创建项目的时候选择预处理器 (Sass/Less/Stylus)。如果当时没有选好，内置的 webpack 仍然会被预配置为可以完成所有的处理。你也可以手动安装相应的 webpack loader：
