-## Introduction
-
-Vue (pronounced `/vjuː/`, like view) is a **progressive framework** for building user interfaces. It is designed from the ground up to be incrementally adoptable, and can easily scale between a library and a framework depending on different use cases. It consists of an approachable core library that focuses on the view layer only, and an ecosystem of supporting libraries that helps you tackle complexity in large Single-Page Applications.
-
-#### Browser Compatibility
-
-Vue.js supports all browsers that are [ES5-compliant](https://kangax.github.io/compat-table/es5/) (IE8 and below are not supported).

-## Explanation of Build Files
-
-| | UMD | CommonJS | ES Module |
-| --- | --- | --- | --- |
-| **Full** | vue.js | vue.common.js | vue.esm.js |
-| **Runtime-only** | vue.runtime.js | vue.runtime.common.js | vue.runtime.esm.js |
-| **Full (production)** | vue.min.js | | |
-| **Runtime-only (production)** | vue.runtime.min.js | | |
-
-### Terms
-
- **Full**: builds that contains both the compiler and the runtime.
-
- **Compiler**: code that is responsible for compiling template strings into JavaScript render functions.
-
- **Runtime**: code that is responsible for creating Vue instances, rendering and patching virtual DOM, etc. Basically everything minus the compiler.
-
- **[UMD](https://github.com/umdjs/umd)**: UMD builds can be used directly in the browser via a `<script>` tag. The default file from Unpkg CDN at [https://unpkg.com/vue](https://unpkg.com/vue) is the Runtime + Compiler UMD build (`vue.js`).
-
- **[CommonJS](http://wiki.commonjs.org/wiki/Modules/1.1)**: CommonJS builds are intended for use with older bundlers like [browserify](http://browserify.org/) or [webpack 1](https://webpack.github.io). The default file for these bundlers (`pkg.main`) is the Runtime only CommonJS build (`vue.runtime.common.js`).
-
- **[ES Module](http://exploringjs.com/es6/ch_modules.html)**: ES module builds are intended for use with modern bundlers like [webpack 2](https://webpack.js.org) or [rollup](http://rollupjs.org/). The default file for these bundlers (`pkg.module`) is the Runtime only ES Module build (`vue.runtime.esm.js`).
-
-### Runtime + Compiler vs. Runtime-only
-
-If you need to compile templates on the fly (e.g. passing a string to the `template` option, or mounting to an element using its in-DOM HTML as the template), you will need the compiler and thus the full build.
-
-When using `vue-loader` or `vueify`, templates inside `*.vue` files are compiled into JavaScript at build time. You don't really need the compiler in the final bundle, and can therefore, use the runtime-only build.
-
-Since the runtime-only builds are roughly 30% lighter-weight than their full-build counterparts, you should use it whenever you can. If you wish to use the full build instead, you need to configure an alias in your bundler.
-
-#### Webpack
-
-``` js
-module.exports = {
-  // ...
-  resolve: {
-    alias: {
-      'vue$': 'vue/dist/vue.esm.js' // 'vue/dist/vue.common.js' for webpack 1
-    }
-  }
-}
-```
-
-#### Rollup
-
-``` js
-const alias = require('rollup-plugin-alias')
-
-rollup({
-  // ...
-  plugins: [
-    alias({
-      'vue': 'vue/dist/vue.esm.js'
-    })
-  ]
-})
-```
-
-#### Browserify
-
-Add to your project's `package.json`:
-
-``` js
-{
-  // ...
-  "browser": {
-    "vue": "vue/dist/vue.common.js"
-  }
-}
-```
-
-### Development vs. Production Mode
-
-Development/production modes are hard-coded for the UMD builds: the un-minified files are for development, and the minified files are for production.
-
-CommonJS and ES Module builds are intended for bundlers, therefore we don't provide minified versions for them. You will be responsible for minifying the final bundle yourself.
-
-CommonJS and ES Module builds also preserve raw checks for `process.env.NODE_ENV` to determine the mode they should run in. You should use appropriate bundler configurations to replace these environment variables in order to control which mode Vue will run in. Replacing `process.env.NODE_ENV` with string literals also allows minifiers like UglifyJS to completely drop the development-only code blocks, reducing final file size.
-
-#### Webpack
-
-Use Webpack's [DefinePlugin](https://webpack.js.org/plugins/define-plugin/):
-
-``` js
-var webpack = require('webpack')
-
-module.exports = {
-  // ...
-  plugins: [
-    // ...
-    new webpack.DefinePlugin({
-      'process.env': {
-        NODE_ENV: JSON.stringify('production')
-      }
-    })
-  ]
-}
-```
-
-#### Rollup
-
-Use [rollup-plugin-replace](https://github.com/rollup/rollup-plugin-replace):
-
-``` js
-const replace = require('rollup-plugin-replace')
-
-rollup({
-  // ...
-  plugins: [
-    replace({
-      'process.env.NODE_ENV': JSON.stringify('production')
-    })
-  ]
-}).then(...)
-```
-
-#### Browserify
-
-Apply a global [envify](https://github.com/hughsk/envify) transform to your bundle.
-
-``` bash
-NODE_ENV=production browserify -g envify -e main.js | uglifyjs -c -m > build.js
-```
