 We're glad you asked! The answer is no. We've gone to great lengths to ensure most of the API is the same and the core concepts haven't changed. It's long because we like to offer very detailed explanations and include a lot of examples. Rest assured, **this is not something you have to read from top to bottom!**

 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 [Browserify](http://browserify.org/). Vue also provides accompanying tools for authoring [Single File Components](../guide/single-file-component.html).

-
-### Terms
-
-- **Full**: builds that contain 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 jsDelivr CDN at [https://cdn.jsdelivr.net/npm/vue](https://cdn.jsdelivr.net/npm/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)**: starting in 2.6 Vue provides two ES Modules (ESM) builds:
-
-  - ESM for bundlers: intended for use with modern bundlers like [webpack 2](https://webpack.js.org) or [Rollup](https://rollupjs.org/). ESM format is designed to be statically analyzable so the bundlers can take advantage of that to perform "tree-shaking" and eliminate unused code from your final bundle. The default file for these bundlers (`pkg.module`) is the Runtime only ES Module build (`vue.runtime.esm.js`).
-
-  - ESM for browsers (2.6+ only): intended for direct imports in modern browsers via `<script type="module">`.
-
-### Runtime + Compiler vs. Runtime-only
-
-If you need to compile templates on the client (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:
-
-```js
-// this requires the compiler
-Vue.createApp({
-  template: '<div>{{ hi }}</div>'
-})
-
-// this does not
-Vue.createApp({
-  render() {
-    return Vue.h('div', this.hi)
-  }
-})
-```
-
-When using `vue-loader` or `vueify`, templates inside `*.vue` files are pre-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 still 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: require.resolve('vue/dist/vue.esm.js')
-    })
-  ]
-})
-```
-
-#### Browserify
-
-Add to your project's `package.json`:
-
-```js
-{
-  // ...
-  "browser": {
-    "vue": "vue/dist/vue.common.js"
-  }
-}
-```
-
-#### Parcel
-
-Add to your project's `package.json`:
-
-```js
-{
-  // ...
-  "alias": {
-    "vue" : "./node_modules/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
-
-In Webpack 4+, you can use the `mode` option:
-
-```js
-module.exports = {
-  mode: 'production'
-}
-```
-
-But in Webpack 3 and earlier, you'll need to use [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
-```
-
-Also see [Production Deployment Tips](deployment.html).
-
-### CSP environments
-
-Some environments, such as Google Chrome Apps, enforce Content Security Policy (CSP), which prohibits the use of `new Function()` for evaluating expressions. The full build depends on this feature to compile templates, so is unusable in these environments.
-
-On the other hand, the runtime-only build is fully CSP-compliant. When using the runtime-only build with [Webpack + vue-loader](https://github.com/vuejs-templates/webpack-simple) or [Browserify + vueify](https://github.com/vuejs-templates/browserify-simple), your templates will be precompiled into `render` functions which work perfectly in CSP environments.
-
-## Dev Build
-
-**Important**: the built files in GitHub's `/dist` folder are only checked-in during releases. To use Vue from the latest source code on GitHub, you will have to build it yourself!
-
-```bash
-git clone https://github.com/vuejs/vue.git node_modules/vue
-cd node_modules/vue
-npm install
-npm run build
-```
-
-## Bower
-
-Only UMD builds are available from Bower.
-
-```bash
-# latest stable
-$ bower install vue
-```
-
-## AMD Module Loaders
-
-All UMD builds can be used directly as an AMD module.
