 ## How to build with Clang on Archlinux by the way
 
-1. Install required and useful tools to develop:
-```
-sudo pacman -S cmake clang vulkan-icd-loader vulkan-headers vulkan-validation-layers vulkan-tools
-```
-2. Install the matching Vulkan drivers for your system:
-```
-# For discrete Nvidia GPUs:
-sudo pacman -S nvidia
-
-# For integrated or discrete Radeon GPUs:
-sudo pacman -S vulkan-radeon
-
-# For integrated or discrete Intel GPUs:
-sudo pacman -S vulkan-intel
-```
-3. Clone the repository and run the following commands:
-```
-mkdir debug
-cd debug
-cmake -DCMAKE_C_COMPILER="/usr/bin/clang" -DCMAKE_CXX_COMPILER="/usr/bin/clang++" -DCMAKE_BUILD_TYPE=Debug ..
-cmake --build .
-```
+Just follow the steps of "How to build with GCC on Archlinux by the way" but replace `gcc` with `clang` and `g++` with `clang++`.
