This document provides instructions for using Lagoa.com, a web-based 3D modeling solution. It outlines 5 steps: 1) creating or importing a 3D model, 2) configuring scene properties, 3) previewing renders, 4) setting iframe properties, and 5) starting code in JavaScript. It then provides code snippets and examples for interacting with 3D scenes programmatically, including applying materials and textures, manipulating lights and cameras, and binding navigation tools.
