I need to detect when an item is delete it, to get some information for that item, but I can't use Visual Studio to create something to get this information, so the only thing I can use is a workflow, but I have no idea of how to achieve this or if is it possible to do it using workflows.
It is not possible to assign workflow to delete item action. But you can create custom action which starts a workflow and then deletes an item. You can check this tutorial
