N400 and arrest, no conviction more than 5 years ago

[Lolitochka]

While sending N400, what should be included in terms of arrest, court docket minutes?
Does one need to send original certified copies of anything, or the Originals, or the copies of certified court docs?
Does one need to write a letter explaining what happened?
thank you

Send copies of court documents showing that charge was dropped . Bring original to interview.
