All the details are available from the Secretary of State's website at https://vote.sos.ri.gov/

It'll tell you where your polling place is, and you can look at a sample ballot there as well, so you'll know what to do. You may receive a postcard with polling place information as well as a booklet with details about the candidates from the League of Women Voters.

Make sure you do some research before voting so you can pick candidates and vote on ballot questions that align with where you want to see the area/state/country to go. No candidate is perfect, but you do have a say in the matter, and this is your opportunity.

I hope this helps!
