How you can watch Prince Harry and Meghan Markle's royal wedding

You don't need a formal invite to take part in the royal wedding. Set your alarm for 5 a.m. ET and tune in.

Cameras are allowed inside the ceremony as Prince Harry marries Meghan Markle on Saturday, May 19, at St. George's Chapel on the grounds of Windsor Castle.

All of us at home will get a chance to see the moments on the couple's big day -- from the ceremony to their vows, her dress, the couple's carriage ride around Windsor greeting the public and all the royal guests and best fashion.

ABC News and "GMA" will have special coverage from 5 to 10 a.m. ET live from Windsor, England. "GMA" co-anchor Robin Roberts and "World News Tonight" anchor David Muir, along with a team of reporters and royal experts, will have live updates and colorful commentary from Windsor and London.

You don't need a TV either. The five hours of special coverage will be available to stream on ABC News' digital platforms including, ABCNews.com and GoodMorningAmerica.com, mobile apps, social platforms and over-the-top (OTT) services.
