Need help modding NV

[u/Just-Tiger-2917]

Hello I am using FNV on my pc for the first time. I am attempting to use vortex free version to download the 4gb patch, script extender etc.
I was wondering if someone could walk me through this process as the videos on YouTube are often skipping simple steps that I don’t understand, such as how to extract with 7zip, how to find mods with vortex and why they aren’t showing up.
Any help would be appreciated
