In the integration guide, you saw how to create a tournament series.
Tournament series are designed to be set up once and then run indefinitely until you decide to stop them.
Currently, you can have one tournament series per game, but in the future, it will be different.
After you created a tournament series, you can edit certain parameters - go to the "Games", select a game and then "Show tourn. template". You can change the tournament name, description, custom prize pool.
You can also pause the tournament series or replace it with a new one.
Those actions are irreversible - your current tournament series will be deleted.
