This document provides instructions for adding 3D text objects to an Alice scene. The instructions state to load Alice, select "Add objects", choose 3D text from the options, type the text and select fonts, then click "OK" to add the text object. Once added, the 3D text works like any other object and can be moved and manipulated using the same skills from previous guides. The document suggests thinking about how to effectively use 3D text to make an advertisement scene.
