The first presidential debate between Joe Biden and Donald Trump is less than two weeks away, and now we know some of the rules.

They include a limit intended to keep candidates from talking over each other. Microphones will be muted for the candidate who is not speaking.

The debate, to be held at CNN Studios in Atlanta, without a studio audience, is the first presidential debate ever hosted in Atlanta between the party nominees.

Here are the rules as announced by CNN and agreed to by both campaigns:

• The debate will be 90 minutes with two commercial breaks. Campaign staff will not be allowed to interact with candidates during the breaks.
• Both candidates will appear at a uniform podium. A coin flip will determine the position of the podiums.
• Microphones will be muted during the debate except for the candidate whose turn it is to speak. Moderators, the network said “will use all tools at their disposal to enforce timing and ensure a civilized discussion.”
• No props or pre-written notes will be allowed on stage. Candidates will have a pen, a pad of paper and a bottle of water.
• There will be no audience in the studio for the debate.
• Hosts for the debate will be CNN’s Jake Tapper and Dana Bash.

How to watch

The debate will air at 9 p.m. June 27 on CNN, CNN International, CNN en Español, CNN Max and on CNN.com. It also will simulcast for other networks.
