 ### For Linux users:
 
+#### Using the LunarG Vulkan SDK
+
 First, follow the official LunarG instructions for the installation and setup of the Vulkan SDK in the [Getting Started with the Linux Tarball Vulkan SDK](https://vulkan.lunarg.com/doc/sdk/latest/linux/getting_started.html) guide.
 
 > [!IMPORTANT]
 > After completing the first step, ensure that you have used the `source` command on the `setup_env.sh` file inside of the Vulkan SDK in your current terminal session. Otherwise, the build won't work. Additionally, if you close out of your terminal, you must perform this step again if you intend to perform a build. However, there are ways to make this persistent. Refer to the Vulkan SDK guide linked in the first step for more information about any of this.
 
+#### Using system packages
+
+On Debian / Ubuntu, you can install the required dependencies using:
+```sh
+sudo apt-get install libvulkan-dev glslc
+```
+
+#### Common steps

 Second, after verifying that you have followed all of the SDK installation/setup steps, use this command to make sure before proceeding:
 ```bash
