WHO VOTES?
WHAT IS THE RITUAL?
The master of liturgical celebrations then cries "Extra omnes," Latin for "all out." Everyone except the cardinals leaves and the voting can begin.

HOW DO THEY VOTE?
Once cast, the ballots are opened one by one by three different "scrutineers," who note the names down and read them aloud. Cardinals can keep their own tally on a sheet of paper provided but must turn their notes in to be burned at the end of voting.
The scrutineers then add up the results of each round of balloting and write the results down on a separate sheet of paper which is preserved in the papal archives.
As the scrutineer reads out each name, he pierces each ballot with a needle through the word "Eligo" and binds the ballots with thread and ties a knot. The ballots are then put aside and burned in the chapel stove along with a chemical to produce either black or white smoke.
Up to four rounds of voting are allowed each day after the first day, and a two-thirds majority — 77 votes — is needed.
If no one is elected after three days — by Friday afternoon — voting pauses for up to one day. Voting resumes and if no pope is elected after another seven ballots, there is another pause, and so on until about 12 days of balloting have passed.
Under norms introduced by Benedict XVI just before he resigned, the cardinals then go to a runoff of the top two vote-getters. A two-thirds majority is required; neither of the two top candidates casts a ballot in the runoff.

WHAT HAPPENS ONCE THE POPE IS ELECTED?
Once a cardinal has been elected pope, the master of liturgical ceremonies enters the Sistine Chapel and the senior cardinal asks "Do you accept your canonical election as Supreme Pontiff?" Assuming the cardinal says "I accept," the senior cardinal then asks: "By what name do you wish to be called?" The master of liturgical ceremonies, Monsignor Guido Marini, then enters the information on a formal document.
At this point, white smoke pours out of the Sistine Chapel chimney and bells of St. Peters toll.
The new pope then changes into his papal white cassock, and one-by-one the cardinals approach him to swear their obedience.
In a change for this conclave, the new pope will stop and pray in the Pauline Chapel for a few minutes before emerging on the loggia of the balcony overlooking St. Peter's Square. Preceding him to the balcony is French Cardinal Jean-Louis Tauran, the protodeacon, who announces "Habemus Papam!" Latin for "We have a pope" and then introduces him to the world in Latin.
The new pope then emerges and delivers his first public words as pope.

FAMOUS FIRST WORDS?
Pope John Paul II charmed the crowd of thousands on Oct. 16, 1978 when he first emerged on the loggia, no easy task given his predecessor had only lived as pope for 33 days and Karol Wojtyla was the first non-Italian elected in 455 years.
Noting that he came from a far-away land — Poland — he told the crowd that he would speak in their ("our") language.
"If I make a mistake, you will correct me," he said to cheers.
Retired Pope Benedict XVI offered a similarly modest gesture on April 19, 2005, telling the crowd he was but a simple "humble worker in the vineyard of the Lord."
