 # MonoGame realtime rendering demo
 
+![MonoGame Demo](../MonoGameDemo.jpg)
+
+Notes on the demo:
+
+MonoGame typically preprocesses all graphics resources through its content pipeline, and all assets are converted to XNB files, which is what the runtime is able to load.
+
+This is not the case of this demo; the glTF files are loaded at runtime without any preprocessing.
+
+Also for simplicity, the demo uses the default in-built BasicEffect and SkinnedEffect shaders, which date from the years of DirectX9, so PBR rendering is not supported.
+
+The project depends on [SharpGLTF.Runtime.MonoGame](..\SharpGLTF.Runtime.MonoGame), which also depends on [SharpGLTF.Core](..\..\src\SharpGLTF.Core), that's everything you need to load and render glTF models into MonoGame.
