+## How to build with GCC on Archlinux by the way
+
+1. Install required and useful tools to develop:
+```
+sudo pacman -S cmake gcc 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/gcc" -DCMAKE_CXX_COMPILER="/usr/bin/g++" -DCMAKE_BUILD_TYPE=Debug ..
+cmake --build .
+```
