+npm is the recommended installation method when building large scale applications with Vue. It pairs nicely with module bundlers such as [webpack](https://webpack.js.org/) or [Rollup](https://rollupjs.org/).
 
 ```bash
 # latest stable
 $ npm install vue@next
 ```
 
+Vue also provides accompanying tools for authoring [Single File Components](../guide/single-file-component.html) (SFCs). If you want to use SFCs then you'll also need to install `@vue/compiler-sfc`:
+
+```bash
+$ npm install -D @vue/compiler-sfc
+```
+
+If you're coming from Vue 2 then note that `@vue/compiler-sfc` replaces `vue-template-compiler`.
+
+In addition to `@vue/compiler-sfc`, you'll also need a suitable SFC loader or plugin for your chosen bundler. See the [SFC documentation](../guide/single-file-component.html) for more information.
+
+In most cases, the preferred way to create a webpack build with minimal configuration is to use Vue CLI.

 ## CLI
 
 Vue provides an [official CLI](https://github.com/vuejs/vue-cli) for quickly scaffolding ambitious Single Page Applications. It provides batteries-included build setups for a modern frontend workflow. It takes only a few minutes to get up and running with hot-reload, lint-on-save, and production-ready builds. See [the Vue CLI docs](https://cli.vuejs.org) for more details.
