 # Webpack Builder for Architect
 
-WIP
+This package allows you to run Webpack and Webpack Dev Server using Architect.
+
+To use it on your Angular CLI app, follow these steps:
+
+- run `npm install @angular-devkit/build-webpack`.
+- create a webpack configuration.
+- add the following targets inside `angular.json`.
+```
+  "projects": {
+    "app": {
+      // ...
+      "architect": {
+        // ...
+        "build-webpack": {
+          "builder": "@angular-devkit/build-webpack:webpack",
+          "options": {
+            "webpackConfig": "webpack.config.js"
+          }
+        },
+        "serve-webpack": {
+          "builder": "@angular-devkit/build-webpack:webpack-dev-server",
+          "options": {
+            "webpackConfig": "webpack.config.js"
+          }
+        }
+      }
+```
+- run `ng run app:build-webpack` to build, and `ng run app:serve-webpack` to serve.
+
+All options, including `watch` and `stats`, are looked up inside the webpack configuration.
