+### Range
+
+The `Range` field is typically a handler for `numeric` model attributes:
+
+```php
+$field = Range::make(__('Points'), 'points')
+    ->min(0)
+    ->max(10);
+```
+
+### Repeater
+
+The `Repeater` field similar to the [`Fieldset`](#fieldset) field, however the sub-fields are repeatable:
+
+```php
+$field = Repeater::make(__('Books'), 'books')
+    ->withFields(static function (): array {
+        return [
+            Text::make(__('Author'), 'author'),
+            Text::make('ISBN'),
+        ];
+    });
+```
+
+You may also set a maximum number of repeatable elements using the `max` method:
+
+```php
+$field->max(4);
+```
+
+### Select
+
+The `Select` field is similar to the [`Checkbox`](#checkbox), [`Dropdown`](#dropdown) and [`Radio`](#radio) fields, in fact the `Select` field is their parent class:
+
+```php
+$field = Select::make(__('Tags'), 'tags')
+    ->options([
+        'bug' => 'Bug',
+        'info' => 'Info',
+        'question' => 'Question',
+    ]);
+```
+
+You may make the field to `nullable` which means an extra empty option is available in the options:
+
+```php
+$field->nullable();
+
+// or
+
+$field->nullable(false);
+```
+
+You can also apply modifiers on `Select` field:
+
+```php
+// Adds the "size" HTML input attribute
+$field->size(10);
+
+// Adds the "multiple" HTML input attribute
+$field->multiple();
+// or
+$field->multiple(false);

+The `Slug` field  is typically a handler for auto-generating URL friendly values of specified model attributes:
 
 ```php
-$field = Range::make(__('Points'), 'points')
-    ->min(0)
-    ->max(10);
+$field = Slug::make(__('Slug'), 'slug')
+    ->from(['name']);
 ```
 
-### Repeater
+You may also want to have unique slugs, which means when a slug is already exists in the databse table, the new slug will get an incremented numeric suffix to avoid conflicts:
 
-### Select
+```php
+$field->unique();
 
-### Slug
+// unique-slug
+// unique-slug-1
+// unique-slug-2
+// etc...
+```
+
+You may also want to customize the slug separator:
+
+```php
+$field->separator('_');
+```
+
+> The default slug separator is `-`.
+
+You may also want to completely customize the slug generation logic:
+
+```php
+use Illuminate\Database\Eloquent\Model;
+use Illuminate\Http\Request;
+use Illuminate\Support\Str;
+
+$field->generateUsing(static function (Request $request, Model $model, string $value): string {
+    return sprintf('%s-%s', $value, Str::random(5));
+});
+```
+
+By default the `Slug` field is generating slug only when creating the model. If you want to run the generation logic when the model is being updated as well, you may call the `always` method:
+
+```php
+$field->always();
+```
