 ### User install (manual)
 1. Build the library:
-  ``nix build``
-3. Create the following path in case it does not exist:
-  ``mkdir -p $HOME/.local/share/vulkan/implicit_layer.d`` 
+  ```bash
+  nix build
+  ```
+2. Create the following path in case it does not exist:
+  ```bash
+  mkdir -p $HOME/.local/share/vulkan/implicit_layer.d

 3. Symlink the build results to your $HOME/.local/
-  ``cp -ifrsv "$(readlink -f ./result)"/* $HOME/.local/``
+  ```bash
+  cp -ifrsv "$(readlink -f ./result)"/* $HOME/.local/
+  ```
 
 ## Usage
 Run a Vulkan application with the environment variable ``ENABLE_LSFG=1`` set.
 
-Example: ``ENABLE_LSFG=1 vkcube`` and look for output like this in the terminal: lsfg-vk(...): ...
+Example:
+```bash
+ENABLE_LSFG=1 vkcube

-You can also enable it per game on Steam by adding this to the launch options of a game like this: 
-  ``ENABLE_LSFG=1 %COMMAND%``
+To confirm that it is working, look for output like this in the terminal: lsfg-vk(...): ...
 
-There are many more options that can be set. Consult the original repository for further documentation.

+>[!NOTE]
+> If the environment variable is set but the program doesn't show any lsfg-vk output, you may need to add the application to your lsfg-vk configuration file at `~/.config/lsfg-vk/config.toml`. Read more about it in the [Wiki](https://github.com/PancakeTAS/lsfg-vk/wiki/Configuring-lsfg-vk)
