# Overview

Genesis World is a simulation platform for physical AI development: a unified multi-physics engine, a photorealistic renderer ([Nyx](https://github.com/Genesis-Embodied-AI/genesis-nyx)), and a cross-platform compiler ([Quadrants](https://github.com/Genesis-Embodied-AI/quadrants)) behind a single Pythonic API, scaling from a laptop CPU to datacenter GPUs without a change to your code.

This section orients you and gets the platform installed before the {doc}`Getting Started </user_guide/getting_started/index>` tutorials begin.
