What does Ruth 4:1 mean?

Meanwhile, Boaz went up to the town gate and sat down there. Just then, the family redeemer he had mentioned came by, so Boaz called out, 'Hey, come over here and sit down.' The man came and sat down. Ruth 4:1 - Modern Text Bible

(Boaz takes initiative to resolve Ruth's situation by meeting the other potential redeemer at the town gate, which was the place for legal matters.)
