How do I import components into KiCAD?

Hello,

Can someone tell me how do I import components into KiCAD?

I've tried to use "Footprint Library Wizard" but the components didn't appear in the libraries,
I've tried to place the component github link in the "Footprint Libraries Manager" but got error when I opened the components list,

How do I do to import components into KiCAD? Am I doing something wrong?

Wait I figured it out!
Actually this way to long video had that info:
