If your team's league runs on the FA's Full-Time system and publishes a public fixtures/results/table page, you can connect that page's URL to your team in Dugout. Once connected, Dugout checks it once a day and refreshes your fixtures, results and league table automatically. There's no manual entry and no separate import needed each week.
This is set up per team, from your Team Admin area, so different teams at the same club can each connect to their own league's page independently. If a refresh ever fails because the league's page changes format or is temporarily unavailable, your existing data stays exactly as it was until the next successful check. Nothing gets wiped out by a failed sync.
