+## Using a custom user model
+
+By default, the `imports` table has a `user_id` column. That column is constrained to the `users` table:
+
+```php
+$table->foreignId('user_id')->constrained()->cascadeOnDelete();
+```
+
+In the `Import` model, the `user()` relationship is defined as a `BelongsTo` relationship to the `App\Models\User` model. If the `App\Models\User` model does not exist, or you want to use a different one, you can bind a new `Authenticatable` model to the container in a service provider's `register()` method:
+
+```php
+use App\Models\Admin;
+use Illuminate\Contracts\Auth\Authenticatable;
+
+$this->app->bind(Authenticatable::class, Admin::class);
+```
+
+If your authenticatable model uses a different table to `users`, you should pass that table name to `constrained()`:
+
+```php
+$table->foreignId('user_id')->constrained('admins')->cascadeOnDelete();
+```
+
+### Using a polymorphic user relationship
+
+If you want to associate imports with multiple user models, you can use a polymorphic `MorphTo` relationship instead. To do this, you need to replace the `user_id` column in the `imports` table:
+
+```php
+$table->morphs('user');
+```
+
+Then, in a service provider's `boot()` method, you should call `Import::polymorphicUserRelationship()` to swap the `user()` relationship on the `Import` model to a `MorphTo` relationship:
+
+```php
+use Filament\Actions\Imports\Models\Import;
+
+Import::polymorphicUserRelationship();
+```
+
 ## Limiting the maximum number of rows that can be imported
 
 To prevent server overload, you may wish to limit the maximum number of rows that can be imported from one CSV file. You can do this by calling the `maxRows()` method on the action:
