How do I install GPT?

Excuse me, could you please clarify the steps involved in installing GPT for me? I'm not entirely familiar with the process and would appreciate it if you could guide me through it. Specifically, I'm wondering if there are any prerequisites that I need to take care of before I begin the installation, and if there are any particular versions of GPT that you would recommend for a beginner like myself. Additionally, I'm curious about the system requirements and whether there are any known compatibility issues that I should be aware of. Thank you in advance for your help.
