To display a layout in the public front end, it should be saved and published.
After you have created your first layout with Kiolezo, close the edit view, then go under templates, and then styles, in Joomla! admin menu.
Here select Kiolezo template as default, or assign it to some pages.
Open it and select from the drop down menu the layout which you want to display as front end template.
Only published layouts are available in the drop down menu, but of course, before to use a template on your front end, you can see the preview from Kiolezo edit view, even if the layout is unpublished.
After the layout is selected and the style is saved, you can click on Upgrade module positions button, which generate automatically into template XML file, all the module positions that you have dragged in your layout.
In this way, you can find your layout's module positions when you edit a module, when you select a new position for it from the drop down menu.
