+## Admin Bar
+
+A deploy button and the status badge of the last build is added to the admin bar. By default this will only be displayed to users that can `manage_options`.
+
+You may allow other user roles with these two filters:
+
+```
+add_filter('netlify_status_capability', function() {
+ return 'edit_pages';
+});
