+
+## Configuration
+
+Configuration is handled via the `pwa` property of either the `vue.config.js`
+file, or the `"vue"` field in `package.json`. 
+
+### pwa.workboxPluginMode
+
+This allows you to the choose between the two modes supported by the underlying
+[`workbox-webpack-plugin`](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin).
+
+- `'GenerateSW'` (default), will lead to a new service worker file being created
+each time you rebuild your web app.
+
+- `'InjectManifest'` allows you to start with an existing service worker file,
+and creates a copy of that file with a "precache manifest" injected into it.
+
+The "[Which Plugin to Use?](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#which_plugin_to_use)"
+guide can help you choose between the two modes.
+
+### pwa.workboxOptions
+
+These options are passed on through to the underlying `workbox-webpack-plugin`.
+
+For more information on what values are supported, please see the guide for
+[`GenerateSW`](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#full_generatesw_config)
+or for [`InjectManifest`](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#full_injectmanifest_config).
+
+### Example Configuration
+
+```js
+// Inside vue.config.js
+module.exports = {
+  // ...other vue-cli plugin options...
+  pwa: {
+    workboxPluginMode: 'InjectManifest',
+    workboxOptions: {
+      // swSrc is required in InjectManifest mode.
+      swSrc: 'dev/sw.js',
+      // ...other Workbox options...
+    },
+  },
+};
+```
