-## Packages
-
-*This section will move to somewhere more global.*
-
-VPE comes in a bunch of Unity packages. There are two reasons there are so many of them:
-
-1. HDRP and URP are incompatible.
-2. We want to separate assets from the code in order to keep the code light.
-
-We haven't got a player project yet. So there are even more packages to come! Anyway, because package names are long
-and there are subtle differences, here's how will be referring to them:
-
-|                         | Package Name                              | Repository                            |
-|-------------------------|-------------------------------------------|---------------------------------------|
-| vpe (also "core") | org.visualpinball.engine.unity            | [VisualPinball.Engine](https://github.com/freezy/VisualPinball.Engine)                  |
-| vpe.hdrp          | org.visualpinball.engine.unity.hdrp       | [VisualPinball.Unity.Hdrp](https://github.com/freezy/VisualPinball.Unity.Hdrp)              |
-| vpe.assets        | org.visualpinball.unity.assetlibrary      | [VisualPinball.Unity.AssetLibrary](https://github.com/freezy/VisualPinball.AssetLibrary/tree/refactor/repos/VisualPinball.Unity.AssetLibrary)      |
-| vpe.assets.hdrp   | org.visualpinball.unity.assetlibrary.hdrp | [VisualPinball.Unity.AssetLibrary.Hdrp](https://github.com/freezy/VisualPinball.AssetLibrary/tree/refactor/repos/VisualPinball.Unity.AssetLibrary.Hdrp) |
-| unity.hdrp              | com.unity.render-pipelines.high-definition | [Unity/Graphics](https://github.com/Unity-Technologies/Graphics/tree/master/com.unity.render-pipelines.high-definition) |

-- **vpe** is the main repo. It contains mainly the code, and some resources, which will 
-  probably move into vpe.unity.assets at some point. It doesn't have any dependencies, neither
-  to any of the other vpe packages nor to Unity's HDRP or URP. If only this repo is used in a 
-  project, the standard renderpipeline is used.
-- **vpe.hdrp** contains HDRP-specific code.
-- **vpe.assets** contains common assets only, i.e. asses that are render pipeline-agnostic.
-- **vpe.assets.hdrp** contains HDRP-specific assets.

-### Dependencies
-
-We have the following dependencies:

-
-So we see that vpe.hdrp pulls in three other dependencies. These have to be added manually at the moment. So when
-working with HDRP, you would have the following packages under *Custom* in the package manager:
-
-- Visual Pinball Engine
-- Visual Pinball Engine (Common Assets)
-- Visual Pinball Engine (HDRP Assets)
-- Visual Pinball Engine (HDRP)
