Well!
That was fast, and informative.
I obtained some mods from the Steam Workshop, by clicking "subscribe".
I obtained some from here, and from Nexus, by manually downloading them, opening the .zip or .rar and putting the folder in the "extensions" folder, in the "Program (x86)>Steam>steamapps>common>X4 Foundations" line.
I just did a search in My Documents, and found an X4 folder there. I'll make an additional "extensions" folder, and try tater trader.
This may take a while. I started having PTSD symptoms about the time they announced X:Rebirth. (The two events are not related). It makes things a bit fuzzy, and time consuming. I'll get back when I've tried that, just...don't haud yer wisht if something else comes up!
Thanks
