There are two ways to access the settings. You can be in the Page Editor mode, and right-click on the site you want to work on and in the context menu select Settings. Alternatively, you can open Site under the File menu, and a context menu will be visible. Click on Site Settings and the following window will open up.

Name - The site name is used only within StudioLine and doesn't have any relationship to the published website.

Folder - Indicates where the website is stored within StudioLine.

Home Page - By browsing through your site, you can choose which page you would like to be treated as the homepage of your site. This will be the first page a browser goes to when users visit.
If you uncheck the Home Page box, the home page currently on the server will be deleted. However it remains saved in your StudioLine files. Nevertheless, all existing navigation links that relate to the home page will become inactive.
