 ### Vulkan Packages
 
 The most important components you'll need for developing Vulkan applications on Linux are the Vulkan loader, validation layers, and a couple of command-line utilities to test whether your machine is Vulkan-capable:
 
-* `sudo apt install vulkan-tools`: Command-line utilities, most importantly `vulkaninfo` and `vkcube`. Run these to confirm your machine supports Vulkan.
-* `sudo apt install libvulkan-dev`: Installs Vulkan loader. The loader looks up the functions in the driver at runtime, similarly to GLEW for OpenGL - if you're familiar with that.
-* `sudo apt install vulkan-validationlayers-dev spirv-tools`: Installs the standard validation layers and required SPIR-V tools. These are crucial when debugging Vulkan applications, and we'll discuss them in the upcoming chapter.

 ### Shader Compiler
 
 We have just about all we need, except we'll want a program to compile shaders from the human-readable  [GLSL](https://en.wikipedia.org/wiki/OpenGL_Shading_Language) to bytecode.
 
-Two popular shader compilers are Khronos Group's `glslangValidator` and Google's `glslc`. The latter has a familiar GCC- and Clang-like usage, so we'll go with that: download Google's [unofficial binaries](https://github.com/google/shaderc/blob/main/downloads.md) and copy `glslc` to your `/usr/local/bin`. Note you may need to `sudo` depending on your permissions. To test, run `glslc` and it should rightfully complain we didn't pass any shaders to compile:
