RGB lighting software for the Corsair M65 Pro

Hi!

I bought a Corsair M65 Pro mouse and to access the RGB lighting functions it says I need to install their proprietary software. Richard Stallman may not have the best ideas but I respect him and I believe that all software should be open source so I don't want to download Corsair's software. Upon further research I found a Github project that's open source and supports RGB lighting for the M65.

Here's the link: https://github.com/ckb-next/ckb-next

My problem is that I've never used github before and I'm unsure of how to continue. I have Debian 10 and I already installed git through the cli with: 'sudo apt-get install git'

What is the syntax that I use to use git to install software from git?

Would it be: 'sudo git //github.com/ckb-next/ckb-next.git'

My second question is that if I use git to install the software at that link will it install everything in the directories in which it's suppossed and basically take care of everything?

Any help would be much appreciated.

Thanks!
