 By default the gem adds the Export button to the partial `views/admin/application/_index_header.html.erb`. But if you have your own Administrate `index` views or override that partial in your application you can add the link manually:
 
 ```ruby
-link_to('Export', [:export, namespace.to_sym, page.resource_name.to_s.pluralize.to_sym, sanitized_order_params(page, :id).to_h.merge(format: :csv)], class: 'button') if existing_action?(resource_class, :export)
+link_to('Export', url_for(sanitized_order_params(page, :id).to_h.merge(action: :export, format: :csv)), class: 'button', target: '_blank', data: { turbolinks: false, turbo: false }) if existing_action?(resource_class, :export) && authorized_action?(resource_name, :export)
 ```
 
 Example:

   </div>
 ....
 ```
 
+The link uses `url_for(action: :export)` so it works regardless of the route name (e.g. models with plural names such as `UserSettings`, whose collection routes end in `_index`), and sets `data-turbolinks="false"`/`data-turbo="false"` so the CSV is downloaded instead of being rendered by Turbolinks/Turbo.
+
+### Associations and performance
+
+Associations (`Field::BelongsTo`, `Field::HasMany`, `Field::HasOne`, `Field::Polymorphic`, ...) that are exported are preloaded automatically to avoid N+1 queries. Associations excluded with `export: false` are not loaded.
+
+If your `transform_on_export` procs access nested associations, you can preload them by overriding `scoped_resource` in your controller:
+
+```ruby
+def scoped_resource
+  return super.preload(organizations: :address) if action_name == "export"
+
+  super
+end
+```
+
 ### Using with Pundit
 
 If you are using [Pundit](https://github.com/varvet/pundit) in your project you will receive an error saying `undefined method 'export?' for #<Admin::OrganizationPolicy>`. This is because the `export` action is not defined in the policy.
