+## Shared HDK Packaging Notes
+
+`hdk-grid` currently has no examples, but it follows the same install-prefix conventions as the rest of HDK.
+
+Under a common install prefix:
+
+- headers install to `${CMAKE_INSTALL_PREFIX}/${CMAKE_INSTALL_INCLUDEDIR}`
+- package metadata installs under `${CMAKE_INSTALL_PREFIX}/${CMAKE_INSTALL_LIBDIR}/cmake/hdk-grid`
+
+Other HDK modules that provide examples install shared assets to `assets` under the same prefix by default, so all HDK outputs remain co-located.
