 one thing to note is that because `formatForListingView` uses `formatForSingleView` internally if you wish to inject something in `formatForSingleView` you will need to inject it in `formatForListingView` as well, otherwise it will not work.
 
+### Global blocks
+
+Global blocks are special blocks that have centralized configuration management. Instead of configuring the same block repeatedly across different pages, you can set up the block configuration once and reuse it everywhere.
+
+#### Creating global blocks
+
+You can create a global block using the make-block command with the `--global` flag:
+
+```bash
+php artisan page-builder-plugin:make-block ContactForm --type=view --global
+```
+
+This will:
+- Create a global block class in `app/Filament/{panel}/Blocks/Globals/` directory
+- Automatically generate a Global Blocks resource for centralized management (on first global block creation)
+- Create the necessary database migration for storing global block configurations
+
+#### How global blocks work
+
+Global blocks use the `IsGlobalBlock` trait and have two key methods:
+
+```php
+<?php
+
+use Redberry\PageBuilderPlugin\Traits\IsGlobalBlock;
+
+class ContactForm extends BaseBlock
+{
+    use IsGlobalBlock;
+
+    // Define the block's schema - this will be used in the Global Blocks resource
+    public static function getBaseBlockSchema(?object $record = null): array
+    {
+        return [
+            TextInput::make('title')->required(),
+            Textarea::make('description'),
+            TextInput::make('email')->email(),
+        ];
+    }
+
+    // The schema returned to the page builder (empty for global blocks)
+    public static function getBlockSchema(?object $record = null): array
+    {
+        $schema = static::getBaseBlockSchema($record);
+        return static::applyGlobalConfiguration($schema);
+    }
+}
+```
+
+#### Global Blocks resource
+
+When you create your first global block, a "Global Blocks" resource is automatically generated in your Filament admin panel. This resource allows you to:
+
+- View all available global blocks
+- Configure each block's field values
+- Edit configurations using the actual Filament form fields defined in `getBaseBlockSchema()`
+
+
+#### Using global blocks on pages
+
+When adding global blocks to pages:
+- **No configuration modal appears** - blocks are added instantly
+- **No per-page configuration** - all configuration is managed centrally
+- **Consistent values everywhere** - the block uses the same configured values across all pages
+
+Simply add your global block to the page builder's blocks array:
+
+```php
+<?php
+
+PageBuilder::make('website_content')
+    ->blocks([
+        ContactForm::class,
+        // other blocks...
+    ]);
+```
+
+#### Key benefits
+
+- **Centralized management**: Configure once, use everywhere
+- **Consistency**: Same content and styling across all instances
+- **Efficiency**: No need to reconfigure the same block on multiple pages
+- **Maintainability**: Update global block configuration in one place
+
 ### Rendering page builder items on infolist
 outside of form you might want to render page builder items on infolist, for this we provide two prebuilt entries:
 `PageBuilderEntry` and `PageBuilderPreviewEntry`
