What is the Scottish referendum?
In nine days time, people across Scotland will face a massive choice - whether or not to become an independent country, separate from the United Kingdom.
A referendum asks you to vote yes or no to a proposal.
The people of Scotland will be asked the simple question: "Should Scotland be an independent country?"
Scotland has been part of the UK for more than 300 years, so the vote is a huge moment for the country.
