Ranked choice voting (RCV) — also known as instant runoff voting (IRV) — makes our elections better by allowing voters to rank candidates in order of preference.
RCV is straightforward: Voters have the option to rank candidates in order of preference: first, second, third and so forth. If your first choice doesn’t have a chance to win, your ballot counts for your next choice.
RCV works in all types of elections and supports more representative outcomes. RCV means better choices, better campaigns, and better representation.

Seems like STV is an extension of ranked choice voting for the special case of multiple-winner elections.
And slightly fancier than approval voting for multiple winner elections.
