# Install Shader Graph

Learn about the Shader Graph installation requirements and follow the installation instructions.

## Requirements

Use Shader Graph with either of the Scriptable Render Pipelines (SRPs) available in Unity version 2018.1 and later:

- The [High Definition Render Pipeline (HDRP)](https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@latest)
- The [Universal Render Pipeline (URP)](https://docs.unity3d.com/Manual/urp/urp-introduction.html)

As of Unity version 2021.2, you can also use Shader Graph with the [Built-In Render Pipeline](https://docs.unity3d.com/Documentation/Manual/built-in-render-pipeline.html).

> [!NOTE]
> - Shader Graph support for the Built-In Render Pipeline is for compatibility purposes only. Shader Graph doesn't receive updates for Built-In Render Pipeline support, aside from bug fixes for existing features. It's recommended to use Shader Graph with the Scriptable Render Pipelines.
> - In the Built-In Render Pipeline, Shader Graph doesn't support XR.
> - In the Built-In Render Pipeline, GPU Instancing doesn't work with Shader Graph shaders.
> - In URP and HDRP, GPU instancing works with custom shaders only if you disable the [Scriptable Render Pipeline (SRP) Batcher](SRPBatcher) or [make a shader incompatible with the SRP Batcher](SRPBatcher-Incompatible).

## Installation

When you install HDRP or URP into your project, Unity also installs the Shader Graph package automatically. You can manually install Shader Graph for use with the Built-In Render Pipeline on Unity version 2021.2 and later with the Package Manager.
