 * `sudo apt install libvulkan-dev` or `sudo dnf install vulkan-loader-devel` : 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` or `sudo dnf install mesa-vulkan-devel vulkan-validation-layers-devel`: 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: on Ubuntu, 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. On Fedora use `sudo dnf install glslc`.  To test, run `glslc` and it should rightfully complain we didn't pass any shaders to compile:
