If you’re one of millions of Americans heading to the polls on Tuesday, there’s some information you should know before you go.

How do I find my polling location?

You can always check with your local board of elections, but Google has also made it very simple to find your polling site. If you type “find my polling place” or similar search terms into Google, it will pull up a box that allows you to type in your address and find your spot. Once you enter your address, it will also tell you the voting requirements for your state.

Who (and what) am I voting for?

After you enter your address in the Google search feature, it will also show you what candidates and measures are on your ballot besides the presidential race. Here, for example, are all the states where medical or recreational marijuana is on the ballot.

What do the latest polls say?

You can find an average of the latest national polls in the presidential race at Real Clear Politics; with less than a week to go, the average had Donald Trump and Hillary Clinton with less than a 2-point gap between them.

What’s at stake?

A lot. TIME’s recent Issues Issue looked at many of the big problems facing the country, from unaffordable childcare to an empty Supreme Court seat and the opioid epidemic.

Can I still register to vote?

If you live in one of just eight states in the country, you can register to vote on Election Day. Here’s a list of the last possible days to register for every state.

How do I know when polls close?

Your best bet is to contact your local board of elections to find out what time polls open and close in your state. Other websites like Ballotpedia have compiled roundups of poll times so you can find them all in one place. In general, polls open at about 7 a.m. and close at about 7 p.m. on Election Day, but that varies by location.

How likely is it that my voting booth gets hacked?

Not very. But take a look at TIME’s map to see what technology your county uses and how vulnerable it may be.

Can I take a ballot selfie?

It depends. Check out our map to find out where ballot selfies are legal. Don’t be like Justin Timberlake.
