How to garrison a unit on G&K?

Hi guys, I am a newbi on the expantion pack, but "veteran" on Civ5 vanilla.

On vanilla if a unit ends its moves on a city it automatically garrisons on it; also on the city, there was a button specifically to garrison it (as well as fortify or do nothing).

Now on K&G it seams that this ability was vanished? is this a stuoid question?

Any (military, land) unit in a city is automatically garrisoned in G&K.

Yes: now a city has a garrison whenever a unit is inside it. This has removed the tedious need to repeatedly garrison your archer, use the city bombard, then fire the arrows while defending. The city gets the extra bombard strength just from having the archer on its tile.

And the "no maintenance unit cost" due to SP Oligarchy is also automatically? I did not checked it out...

Yup, it's all done automatically. It's really a big help - if I now have a unit traveling that passes over a city, I don't have to pull it out of garrison anymore before it does anything. The No Maintenance from Oliarchy is indeed automatically done, yes.
