    Open your project in Unreal Engine, go to **Edit → Plugins**, search for **xrliveSDK** and enable it. Restart the editor when prompted.

  <Step title="Compile">
    The editor will detect new C++ modules and prompt you to compile. Click **Yes**. First compile may take a few minutes.

## Plugin modules

The SDK is split into two modules:

| Module              | Purpose                                               |
| ------------------- | ----------------------------------------------------- |
| `xrliveSDK`         | Runtime — all Blueprint nodes, subsystems, components |
| `xrliveSDKPackager` | Editor-only — the `.xrlive` export tool               |
