+The module defaults work well with [Lupus Decoupled Drupal](https://www.drupal.org/project/lupus_decoupled), so setting the `baseURL` is usually enough.

+## Features
+
+* Fetches pages via the custom elements API provided by the [Lupus Custom Elements Renderer](https://www.drupal.org/project/lupus_ce_renderer) 
+* Provides a Nuxt-wildcard route, so all Drupal pages can be rendered via Nuxt.js and vue-router.
+* Integrates page metadata and the page title with Nuxt.
+* Supports breadcrumbs and local tasks ("Tabs")
+* Supports authenticated requests. Cookies are passed through to Drupal by default.
+* Supports display of Drupal messages in the frontend.
+* Provides unstyled skeleton components for getting started quickly.
+* Supports fetching and display of Drupal menus via the [Rest menu items](https://www.drupal.org/project/rest_menu_items) module.

 ## Options
 
 - `baseURL`: The Drupal base URL. Defaults to the `DRUPAL_BASE_URL`
    environment variable if provided, otherwise to `http://localhost:8888`.
 
+- `fetchOptions`: The default [fetchOptions](https://nuxt.com/docs/api/composables/use-fetch#params)
+   to apply when fetching from the Drupal. Defaults to `{ credentials: 'include' }`.
+
+- `fetchProxyHeaders`: The HTTP request headers to pass through to Drupal, via [useRequestHeaders](https://nuxt.com/docs/api/composables/use-request-headers#userequestheaders). Defaults to `['cookie']`.
+
 - `menuEndpoint`: The menu endpoint pattern used for fetching menus. Defaults to 'api/menu_items/$$$NAME$$$' as fitting
   to the API provided by the [Rest menu items](https://www.drupal.org/project/rest_menu_items) Drupal module.
   `$$$NAME$$$` is replaced by the menu name being fetched.
