# Config The config file accepts dot notatation, a standard array, or a combination of these. **Dot notation;** ```php return [ 'wp-admin.$role|$username.common.adminbar.wp', 'wp-admin.$role|$username.common.adminbar.new', 'wp-admin.$role|$username.common.adminbar.edit', 'wp-admin.$role|$username.common.adminbar.view', ]; ``` **Standard array;** ```php return [ 'wp-admin' => [ '$role|$username' => [ 'common' => [ 'adminbar' => [ 'wp', 'new', 'edit', 'view' ], ], ], ], ]; ``` **Combination;** Using these approaches interchangeably can help bring readability and structure to the config file. ```php return [ 'wp-admin.$role|$username' => [ 'common.adminbar', => [ 'wp', 'new', 'edit', 'view' ], ], ]; ```
