Wanting to install Sequoia onto my Late 2013 iMac. Any recommendations?

Hey everyone. So I own a 21.5-inch Late 2013 iMac that runs on Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina (the last officially supported OS), and have been thinking of using OpenCore to my computer running on Sequoia, as I am a little bit too short on change to purchase a new one that runs on the latest OS.

I've also been watching a few videos and how-to guides on how to install on unsupported systems on old iMacs, but have been a bit hesitant to go through and run an install myself, as i am admittedly a bit technologically illiterate. Is there anything i should know before thinking of installing Sequoia?

My specifications are as follows:

Processor: 2.7 GHz Quad-Core Intel Core i5

Memory: 8 GB 1600 MHz DDR3

Graphics: Intel Iris Pro 1536 MB
