The hearse carrying Queen Elizabeth II's coffin has left Balmoral Castle, beginning a multi-day journey back to England.
The royal family has released details of the plan for the Queen's funeral, and it's full of tradition, protocol and logistics.
The plan for the Queen's death is code-named Operation London Bridge, but another plan called Operation Unicorn is taking place to transport her body from Balmoral Castle in Scotland.
Over the next 10 days, we will see the carefully choreographed plans swing into action.

Where are royal family members right now?
Earlier, King Charles and the Queen Consort were at St James's Palace in London where he was officially proclaimed as King.
His proclamation was witnessed by dignitaries and his son, Prince William.
The Queen's other three children — Anne, Edward and Andrew — and their families were still at Balmoral.
The group attended a short church service before walking back up to the gates of Balmoral Castle, thanking people who had gathered.
Prince Andrew's appearance was notable because he had been largely excluded from royal duties after allegations of sexual assault.
Princes William and Harry, and their wives Catherine and Meghan, were earlier at Windsor Castle where they made a joint appearance to greet people at the gates.
