 # shex: SHader + HEX
-Hex viewer for Linux using Vulkan via GLFW3
+Hex viewer for Linux and FreeBSD using Vulkan via GLFW3
 
 This GUI program is written in C++ and requires hardware that supports Vulkan.
 It depends on vulkan and glfw3
 
 To build: type inside the shex/ directory:
 
-./mk
+make
 
-If you modify the shaders/shader.frag, then you will need xxd to rebuild it.
+If you modify the shaders/shader.frag, or shaders/shader.vert then you will need to rebuild it.
 Just type:
 
-./shmk
+make shaders
 
-and the script will re-generate the frag.h and vert.h. You will need to rebuild
-the executable after that with ./mk script mentioned above.
+after that shaders/frag.spv and shaders/vert.spv will be regenerated.
+There is no need to rebuild an executable after shader changes.
 
 To test: run the executable file with any binary file as parameter
 
 ./shex shaders/frag.spv
 
-There is a windows build command 'mkwin', which allows to cross-compile a
-windows binary on linux. I'm not sure it's working, but if you want to test
