 ## Usage
 
+If you are unfamiliar with Laravel Scout, we suggest reading it's [documentation](https://laravel.com/docs/8.x/scout) first.

 After you have installed scout and the Typesense driver, you need to add the
 `Searchable` trait to your models that you want to make searchable. Additionaly,
 define the fields you want to make searchable by defining the `toSearchableArray` method on the model and implement `TypesenseSearch`:

 ```
 
 Then, sync the data with the search service like:
 
-`php artisan scout:import App\\Post`
+`php artisan scout:import App\\Models\\Todo`
 
 After that you can search your models with:
 
-`Post::search('Bugs Bunny')->get();`
+`Todo::search('Test')->get();`
 
 ## Adding via Query
 The `searchable()` method will chunk the results of the query and add the records to your search index. Examples:
 
 ```php
-$post = Post::find(1);
-$post->searchable();
+$todo = Todo::find(1);
+$todo->searchable();
 
-$posts = Post::where('year', '>', '2018')->get();
-$posts->searchable();
+$todos = Todo::where('created_at', '<', now())->get();
+$todos->searchable();
 ```
