In this section of the site management page, you can manage the themes that are used in your installation. You can set default themes, disable themes and add new themes.

The themes listed here are the ones used when creating a new default project (for XOT, Bootstrap and Decision Tree). It is possible to enter a different default theme here. That means that when an author starts an empty project, it automatically gets the theme indicated here. This can be your own institutional theme, for example, if you have one. If this value is updated, it does not affect projects that have already been created.
