 - `src/index.js` => `dist/index.js`
 
+#### Excluding a page from chunks
+
+If you want a page to be excluded from either the [vendor](#vendor) or [common](#common) chunk, then you can do so by providing an object with a `name` and `independent` flag (set to `true`) instead of just the name of the page.
+
+```js
+// sagui.config.js
+module.exports = {
+  pages: ['index', { name: 'about', independent: true }]
+}
+```
+
+### `chunks`
+
+When multiple pages are configured, it's a good practice to bundle external or common dependencies of your pages into their own chunks in order to reduce the size of the built pages. This can be done with the following flags:
+
+#### `vendor`
+
+If you want all your external dependencies in your [pages](#pages) to be bundled together in a "vendor" chunk, then set this flag to `true`. By default it is set to `false`.
+
+```js
+// sagui.config.js
+module.exports = {
+  chunks: {
+    vendor: true
+  }
+}
+```
+
+#### `common`
+
+If you do not want all the common dependencies of your [pages](#pages) to be bundled together in a "common" chunk, then set this flag to `false`. By default it is set to `true`.
+
+```js
+// sagui.config.js
+module.exports = {
+  chunks: {
+    common: false
+  }
+}
+```
+
 ### `libraries`
 
 Create **reusable libraries** that can be shared across applications. Sagui will take care of the build process so that external libraries are not bundled and that you have a CommonJS module as the output.

When Webpack fails to resolve a dependency, Karma doesn’t get notified at all about the broken build, and the process just hangs.

Transpilation errors behave as expected.
