Today is a historic day for the global Catholic Church: the start of the conclave to elect a new pope. 115 Cardinals will gather to pray and vote. 58 percent of them were made cardinals by Pope Emeritus Benedict XVI, meaning that most have never before participated in a conclave. White smoke and bells will signal that two-thirds majority have voted for a “winning” candidate; black smoke and silence indicate the need for additional votes.

This infographic from the Washington Post details the conclave proceedings.
