 This makes use of the theme system. Create a folder for your theme within your BookStack `themes` directory. As an example we'll use `my_theme`, so we'd create a `themes/my_theme` folder.
 You'll need to tell BookStack to use your theme via the `APP_THEME` option in your `.env` file. For example: `APP_THEME=my_theme`.

 ## Available Events
 
 All available events dispatched by BookStack are exposed as static properties on the `\BookStack\Theming\ThemeEvents` class, which can be found within the file `app/Theming/ThemeEvents.php` relative to your root BookStack folder. Alternatively, the events for the latest release can be [seen on GitHub here](https://github.com/BookStackApp/BookStack/blob/release/app/Theming/ThemeEvents.php).

+## Custom Command Registration Example
+
+The logical theme system supports adding custom [artisan commands](https://laravel.com/docs/8.x/artisan) to BookStack.
+These can be registered in your `functions.php` file by calling `Theme::registerCommand($command)`, where `$command` is an instance of `\Symfony\Component\Console\Command\Command`. 
+
+Below is an example of registering a command that could then be ran using `php artisan bookstack:meow` on the command line.
+
+```php
+<?php
+
+use BookStack\Facades\Theme;
+use Illuminate\Console\Command;
+
+class MeowCommand extends Command
+{
+    protected $signature = 'bookstack:meow';
+    protected $description = 'Say meow on the command line';
+
+    public function handle()
+    {
+        $this->line('Meow there!');
+    }
+}
+
+Theme::registerCommand(new MeowCommand);

+In some cases you may need to customize the driver before it performs a redirect. 
+This can be done by providing a callback as a fourth parameter like so:
+
+```php
+Theme::addSocialDriver('reddit', [
