+    }
+}
+```
+
+Since `\Yiisoft\Yii\Console\CommandLoader` uses lazy loading of commands, it is necessary
+to specify the name and description in static properties when creating a command:
+
+```php
+use Symfony\Component\Console\Command\Command;
+
+final class MyCustomCommand implements Command
+{
+    protected static $defaultName = 'my/custom';
+    protected static $defaultDescription = 'Description of my custom command.';
+
+    protected function configure(): void
+    {
+        // ...
     }
+
+    protected function execute(InputInterface $input, OutputInterface $output): in
+    {
+        // ...
+    }
+}
 ```
 
+> When naming commands, a slash `/` should be used as a separator. For example: `user/create`, `user/delete`, etc.
+
+
 Since the package is based on [Symfony Console component](https://symfony.com/doc/current/components/console.html),
 refer to its documentation for details on how to use the binary and create your own commands.
 
+### Aliases and hidden commands
+
+To configure commands, set the names and aliases in `\Yiisoft\Yii\Console\CommandLoader` configuration.
+Names and aliases from the command class itself are always ignored.
+
+The command can be marked as hidden by prefixing its name with `|`.
+
+
+```php
+'yiisoft/yii-console' => [
+	'commands' => [
+		'hello' => Hello::class, // name: 'hello', aliases: [], hidden: false
+		'start|run|s|r' => Run::class, // name: 'start', aliases: ['run', 's', 'r'], hidden: false
+		'|hack|h' => Hack::class, // name: 'hack', aliases: ['h'], hidden: true
+	],
+],
+```
