A town charter is like a set of rules for how a town works. It's like the instructions for a game that everyone has to follow so that the game is fair and everyone can play without fighting. The charter tells people who are in charge of running the town and what their jobs are. It also talks about things like when the town meetings will happen, how to vote, what the town can spend money on, and what the town can't do. A town charter is important because it helps make sure that everyone knows what is going on in the town, and it helps everyone work together to make the town a better place.
