+# @rollup/plugin-inject
+
+🍣 A Rollup plugin which scans modules for global variables and injects `import` statements where necessary.
+
+## Requirements
+
+This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
+
+## Install
+
+Using npm:
+
+```console
+npm install @rollup/plugin-inject --save-dev
+```
+
+## Usage
+
+Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
+
+```js
+import inject from '@rollup/plugin-inject';
+
+export default {
+  input: 'src/index.js',
+  output: {
+    dir: 'output',
+    format: 'cjs'
+  },
+  plugins: [
+    inject({
+      Promise: ['es6-promise', 'Promise']
+    })
+  ]
+};
+```
+
+Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
+
+This configuration above will scan all your files for global Promise usage and plugin will add import to desired module (`import { Promise } from 'es6-promise'` in this case).
+
+Examples:
+
+```js
+{
+  // import { Promise } from 'es6-promise'
+  Promise: [ 'es6-promise', 'Promise' ],
+
+  // import { Promise as P } from 'es6-promise'
+  P: [ 'es6-promise', 'Promise' ],
+
+  // import $ from 'jquery'
+  $: 'jquery',
+
+  // import * as fs from 'fs'
+  fs: [ 'fs', '*' ],
+
+  // use a local module instead of a third-party one
+  'Object.assign': path.resolve( 'src/helpers/object-assign.js' ),
+}
+```
+
+Typically, `@rollup/plugin-inject` should be placed in `plugins` _before_ other plugins so that they may apply optimizations, such as dead code removal.
+
+## Options
+
+In addition to the properties and values specified for injecting, users may also specify the options below.
+
+### `exclude`
+
+Type: `String` | `Array[...String]`
+Default: `null`
+
+A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should _ignore_. By default no files are ignored.
+
+### `include`
+
+Type: `String` | `Array(String)`
+Default: `null`
+
+A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should operate on. By default all files are targeted.
