 source setup-env.sh into your current shell
 
+Actually, I think now this should work, after following the online instructions for installing Vulkan:
+sudo apt-get install libglm-dev libsdl2-dev libsdl2-image-dev libsdl2-gfx-dev libsdl2-ttf-dev
+
 make vulkangame && ./vulkangame
+
+For the sfml version: (these directions need verification)
+
+sudo apt-get install libglm-dev libsfml-dev
+
+Currently, the apt-get package doesn't have Vulkan support, so need to install from source as follows:
+
+Build the library yourself by following the instructions at https://www.sfml-dev.org/tutorials/2.5/compile-with-cmake.php
+
+sudo apt-get install libfreetype-dev libx11-dev libxrandr-dev libudev-dev libopengl-dev libflac-dev libogg-dev libvorbis-dev libopenal-dev libpthread-stubs0-dev
+
+sudo apt-get install cmake-qt-gui
