It's a pretty straight forward exercise, download the app, download macOS, run the app, install macOS. The only catch is that you need to have a metal compatible graphics card. But for the most part just following this guide and it's pretty straightforward: https://dortania.github.io/OpenCore-Legacy-Patcher/

There's a thread were this is being discussed: https://forums.macrumors.com/threads/macos-12-monterey-on-unsupported-macs-thread.2299557/

Have you updated your computers Boot ROM prior to starting the OpenCore installation? If I remember corrrectly it's required that you be on version 144-XXX. I'm not sure what version of macOS you've been running up until this point, if it's been Mojave, then you already have the updated Boot ROM version.
