The quickest way to get started with uiPress is by import a pre-made template. uiPress comes with a library of templates and they can be accessed through the uiBuilder.
The uiBuilder can be accessed through the main admin menu settings > uiBuilder
From there, click new template and you will be launched into the uiBuilder. On the left panel there is a tab called ‘Library’. From here you can access pre built templates, admin pages, sections and patterns.

Items in the library can either be dragged into your template or you click the download icon and they will be added to the end of your template.
