# OnAboutScript

The **OnAboutScript** event can be implemented by a [script add-in](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/script_add-ins) to display an "about" dialog to the user. It is triggered when the user clicks the *About* button for a script on the [**Script Management**](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/script_management) dialog.
