The conclave to select the next pope is set to begin.
The cardinals wrapped up there general congregation Monday and will begin the process of voting Tuesday.
115 cardinal electors will choose the 266th pope.
Once inside the Sistine Chapel, the cardinals will swear under oath to observe the rules and maintain secrecy.
Each cardinal will write their choice on a small ballot paper, then walk up one by one and deposit the paper into an urn on the altar.
Papers are counted by three cardinals; One will read out the names.
A two-thirds majority is required to select a pope.
After the first vote – if no pope is chosen – there will be two ballots each morning and two each afternoon until a pope is elected.
Ballot papers are burned in a stove inside the Sistine Chapel. If there is no consensus, the smoke will be black. If the smoke is white, a new pope has been chosen.
The first vote will take place Tuesday afternoon.
