# Welcome

Games are better when we play together.

## coherence 0.10.15

### Get started

**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.

### Use Lens search in docs for AI-powered answers

When you use our search bar, you can now switch from *Search* to **Lens**. Simply tell Lens what you want, or ask it a question. It’ll use AI to scan **coherence** documentation and give you a simple, semantic answer — with clickable references if you want to dive deeper.

### Update an existing project

If you are an existing user and looking to update, check out the latest [Release Notes](/0.10/overview/release-notes.md). And maybe the [SDK update guide](/0.10/additional-resources/sdk-update-guide.md) as well!

### Tutorial project

[First Steps](/0.10/learning-coherence/first-steps-tutorial.md) is a collection of articles and scenes showing you how to use various features of the **coherence Unity SDK**. It shows you how to synchronize transforms, physics, persistence, animations, AI navigation and send network commands.

### Existing or new Unity project

You can follow our step-by-step guide 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.
