With only three weeks until the General Election, Donald Trump and Hillary Clinton are set to meet in Las Vegas Wednesday for the final presidential debate.

While there are a series of topics debate moderator Chris Wallace will draw questions from, it’s likely that the candidates will come up with their own topics - for Clinton, Trump’s remarks about women and his fitness to serve; for Trump, Clinton’s email scandals and the continuing release of information about the campaign and the Clinton Foundation’s workings via WikiLeaks.

Here's a quick look at the logistics for the thrid debate.

What time does it start?

The debate begins at 9 p.m. (ET). It will be 90 minutes long, without commercial interruption.

Where can I see it?

The debate will be broadcast live on cable news networks, the three major networks and other media outlets including social media.

Where is it being held?

The debate is being held at the University of Nevada in Las Vegas (UNLV).

Who will moderate the debate?

Chris Wallace, the anchor of Fox News Sunday, will moderate the final debate.

What is the structure for the debate?

The debate will be divided into six 15-minute segments covering topics picked by Wallace. Both candidates will have 2 minutes to respond to a question and then another chance to respond to their opponent. Wallace will use the leftover times to expand on the discussion topic.

What are the topics?

The six topics will be immigration, entitlements and debt, the Supreme Court, the economy, foreign policy, and each candidate's fitness to serve as president.

Will anyone else be on the debate stage?

No, the Libertarian candidate, Gary Johnson, and the Green Party candidate, Jill Stein, both failed to meet the 15 percent polling threshold to qualify for the debate.

Special guests?

Donald Trump has invited Pat Smith to attend the debate. Smith is the mother of Sean Smith, a State Department IT consultant who was killed in the 2012 Benghazi terrorist attacks. Smith, who spoke at the Republican National Convention in July, is an outspoken critic of Hillary Clinton and says she blames her son’s death personally on Clinton.

Time Magazine is reporting that Trump has invited President Barack Obama's half-brother to attend the debate. Malik Obama, who is now an American citizen, announced in July that he supports Trump.

Hillary Clinton has invited Mark Cuban and Meg Whitman to the debate.
