Removing a city

[Thunderhit]

Hello. I want to remove a city from my game. I guess I should use Firetuner for this? I looked around for information on how to use it and what I should write in LUA, but found only something about resetting a unit.
Is there a way to do this?

in FireTuner, go to the map tab and select City Plopper, from there select the correct civ that the city is owned by and right click the city plot. If the city is a capitol, (Which idk if it'll still work in that case) then become that civ through tuner and delete the palace, go back to the other civ you were and delete the city.
