# Welcome

## **coherence 2.1**

**coherence** is a network engine, platform and a series of tools to help anyone create a multiplayer game. Our mission is to give any game developer, regardless of how technical they are, the power to make a connected game.

### Get started

If you would like to get started right away, you can check the [Installation](https://docs.coherence.io/getting-started/installation) page to learn how to install **coherence in Unity**, set up your Scene, Prefabs, interactions, as well as deploy your project to be shared with your friends.

### Learn

To learn how to use **coherence**, we recommend you start by exploring the [**package Samples**](https://docs.coherence.io/getting-started/samples-and-tutorials/package-samples) included right inside the Unity SDK. Or download one of our pre-made Unity projects [First Steps](https://docs.coherence.io/getting-started/samples-and-tutorials/first-steps-tutorial) or [Campfire](https://docs.coherence.io/getting-started/samples-and-tutorials/campfire-project), which both come with extensive documentation explaining the thinking behind them.

If you enjoy learning with videos, we have a [playlist of videos](https://www.youtube.com/playlist?list=PLnHFD0m6ywmNY4CEE99U7vkaq2Vrk9FvS) dedicated to getting started with the Unity SDK.

Finally, if you're new to networking you might enjoy our [Beginner's Guide to Networking](https://docs.coherence.io/getting-started/samples-and-tutorials/beginners-guide-to-networking). This high-level introduction is not coherence-specific, but rather is applicable to any networking technology.
