It will ask users on Discord to write checkin which creates a link between Discord username, challonge team and a seat number (used for LAN parties).
When an Challonge administrator has marked a new match as started, it will be posted on Discord, and it will tag the team captains, such that they get an notification that their match is about to start. Meanwhile the participants also knows who they are going to play against and where they are located at the netparty.
