+## Customizing Actions
+
+To enable or disable certain actions you could override `valid_action?` method in your dashboard controller like this:
+
+```ruby
+# disable 'edit' and 'destroy' links
+def valid_action?(name, resource = resource_class)
+  %w[edit destroy].exclude?(name.to_s) && super
+end
+```
+
+Action is one of `new`, `edit`, `show`, `destroy`.
