+#### Indexing widget
+
+The Algolia plugin includes a Panel widget that allows Panel users to manually index the site. You can disable this widget with the following option:

+```php
+c::set('algolia.widget', false);

 This will create a new temporary index, upload all indexable pages and replace the main index with the temporary index.
 Please note that manual indexing will use roughly as many Algolia "Operations" as you have indexable pages each time you call the `index` method. The amount of included/free "Operations" per month depends on your Algolia plan.
 
+There is also a Panel widget for this that is enabled by default.

 ## Search
 
 The plugin also provides a method to query/search the index from the backend. It is generally recommended to use [Algolia's JavaScript library](https://www.algolia.com/doc/javascript#quick-start) to avoid the round-trip to your server, but you should also have a server-side fallback results page, which you can implement using the `search` method:
