How to play Guild of Guardians on PC?

Hello there, I'm curious about something. I've heard about this game called Guild of Guardians and I'm really interested in trying it out, but I'm not sure how to play it on my PC. Could you possibly provide me with a step-by-step guide on how to get started? I'm not very tech-savvy, so the simpler the instructions, the better. Also, do I need to download any specific software or programs to play the game? Thank you in advance for your help!
