+
+[![npm version](https://img.shields.io/npm/v/pnp-webpack-plugin.svg)](https://www.npmjs.com/package/pnp-webpack-plugin)
+[![node version](https://img.shields.io/node/v/pnp-webpack-plugin.svg)](https://www.npmjs.com/package/pnp-webpack-plugin)
+
+*This plugin is also available for Jest ([jest-pnp-resolver](https://github.com/arcanis/jest-pnp-resolver)), Rollup ([rollup-plugin-pnp-resolve](https://github.com/arcanis/rollup-plugin-pnp-resolve)), and TypeScript ([ts-pnp](https://github.com/arcanis/ts-pnp))*
+
+## Installation
+
+```
+yarn add -D pnp-webpack-plugin
+```
+
+## Usage
+
+Simply add the plugin to both the `resolver` and `resolveLoader`:
+
+```js
+const PnpWebpackPlugin = require(`pnp-webpack-plugin`);
+
+module.exports = {
+  resolve: {
+    plugins: [
+      PnpWebpackPlugin,
+    ],
+  },
+  resolveLoader: {
+    plugins: [
+      PnpWebpackPlugin.moduleLoader(module),
+    ],
+  },
+};
+```
+
+The `resolve` entry will take care of correctly resolving the dependencies required by your program, and the `resolveLoader` entry will help Webpack find the location of the loaders on the disk. Note that in this case, all loaders will be resolved relative to the package containing your configuration.
+
+In case part of your configuration comes from third-party packages that use their own loaders, make sure they use `require.resolve` - this will ensure that the resolution process is portable accross environments (including when Plug'n'Play isn't enabled), and prevent it from relying on undefined behaviors:
+
+```js
+module.exports = {
+  module: {
+    rules: [{
+      test: /\.js$/,
+      loader: require.resolve('babel-loader'),
+    }]
+  },
+};
+```
