+The plugin supports three display modes:
+
+#### 1. Card Grid (Default)
+Files displayed as cards in a grid. Click to open modal.
+
+```php
+FileViewEntry::make('attachments')
+    ->grid(4)
+    ->downloadable();
+```
+
+#### 2. Compact List
+Files displayed as a simple list (icon + filename). Click to open modal.
+
+```php
+FileViewEntry::make('attachments')
+    ->showAsLink(true)         // Compact list view
+    ->downloadable();
+```
+
+#### 3. Inline Display
+Files displayed directly on the page with full preview.
 
 ```php
-// Show files directly on the page instead of in a modal
 FileViewEntry::make('attachments')
     ->asModal(false)           // Display content inline
     ->downloadable()
     ->grid(2);
 ```
