+This project is currently focused on exposing the top level USD api and the schemas on top of
+those as much as possible. Everything related to UsdStage, UsdPrim and where necessary the
+lower level types should be exposed, such as VtValue.
+
+The intention is that later on the higher performance sdf and hydra apis are also exposed.
+
+# Progress
+This is a checklist of the state of exposed objects in the
+USD libraries. If the library is not listed then nothing is
+exposed.
