# Upload a Prefab

## What is a "Meta Prefab"?

"Prefab" is a short form of the word "Prefabrication". A Meta Prefab is similar to a Meta Space, except rather than an entire scene, it's just a single object. These objects can be small or large, and can be loaded into any scene at runtime using the `Meta Prefab Loader` component.

Before getting started, make sure you've properly [installed the SDK](https://reach-cloud.gitbook.io/reach-explorer-documentation/metaverse-cloud-engine-sdk/unity-engine-sdk/how-to-install-the-sdk) and [created an account](https://reach-cloud.gitbook.io/reach-explorer-documentation/metaverse-cloud-engine-sdk/unity-engine-sdk/create-an-account)!

1. With your Unity prefab selected in the **Project** panel, add the `Meta Prefab` component.
