Here are five things to know about the deal, which runs nearly 100 pages.

1. Iran agreed to a continuation of a United Nations arms embargo for up to five years. It could end earlier if the International Atomic Energy Agency agrees, The Associated Press reported. There is also a restriction on the transfer of ballistic missile technology to Tehran. That ban can last up to eight more years. Obama, in a statement to the nation Tuesday morning said, "Iran will get rid of 98 percent of its nuclear material." The country will also remove two-thirds of its centrifuges and will modify its reactor so it cannot enrich uranium.

2. U.N. inspectors can request visits to Iranian military sites as part of their monitoring duties, but the access isn't guaranteed and could be delayed, The Associated Press reported.

3. Iran has an economic benefit to the tune of more than $100 billion. The money comes from assets frozen overseas. The deal also ends a European oil embargo and financial restrictions on Iranian banks on the day the deal is implemented.

4. The deal has the support of Iranian President Hassan Rouhani, who went to Twitter to speak about the negotiations. Iranian foreign minister, Javad Zarif called it a "new chapter of hope," The Associated Press reported.

The European Union is calling it a "sign of hope for the entire world," the BBC reported.

Israeli Prime Minister Benjamin Netanyahu has been against the negotiations from the beginning. He posted to his Twitter account his opposition to the deal.

5. Congress has 60 days to review and agree to the accord. But lawmakers are expected to pick apart the agreement. President Obama threw down the gauntlet to Congress, saying "It would be irresponsible to walk away from this deal. I welcome a robust debate in Congress." He continued, "I would remind Congress that you don't make deals like this with your friends. I will veto any legislation that prevents the implementation of this deal," the BBC reported.
