Open the management of content templates for pages/objects. In the following overview,
you can use the"Edit templates" button to edit existing templates and define new templates for the relevant directory.

requirements. As soon as you save the file, it is available to editors with the appropriate authorization as a template for new files.

If you would like to edit the existing templates, you can also use the"Edit templates" button to switch to the directory of available templates and edit them like normal
pages.
