-## Usage Instructions
+### Usage Instructions
 
 - Disable `Secure Boot` in the BIOS. (Unknown: Applying the Secure Boot certificate to UEFI may enable compatibility.)
 - Download the official build from the [Releases](https://github.com/AppleOSX/UXTU4Unix/releases).
 - Run `UXTU4Unix.command` (macOS only) or run `UXTU4Unix.py` using the command: `python3 /path/to/UXTU4Unix.py` or `python /path/to/UXTU4Unix.py`.
 - Follow the on-screen instructions.
 - [macOS only] For enhanced temperature management and control with `UXTU4Unix`, disable `Core Performance Boost` in the BIOS using [Smokeless_UMAF](https://github.com/DavidS95/Smokeless_UMAF). Note that this may significantly reduce CPU performance, as the `Core Performance Boost` feature on macOS is not optimal.
