# Stored entities

Manage entities that you store as assets on disk.

## Overview

Overview If you bundle 3D assets with your app, or download them from the network into local file storage, you need a way to load them at runtime. RealityKit provides a collection of methods that you use to load USD and Reality files into Entity instances.
