This will copy content into /My Games/Sid Meier's Civilization VI/Mods/'. Alternatively, you can press Ctrl+Shift+B (assuming you haven't changed the defaults).

A mod could be as simple as tweaking the costs of some units and buildings, changing the AI so that it plays differently or adding a new civilization to the game. This mod reskins Civ 6 to look like Civ 5.
