To get started, first, you need to install Unity Hub. Once Unity Hub is installed, proceed to install Unity version 2021.3.12f1. After that, download the source code from the GitHub repository: https://github.com/SebLague/Digital-Logic-Sim and extract it to a suitable location on your computer.
Next, open Unity Hub and navigate to the folder where you extracted the source code. Select the folder to open the entire code project in Unity. Finally, you can follow my tutorial on YouTube to get it working.
