The season is the largest container: everything that is imported ends up inside one.
What you see
The list of seasons with the period of each one.
What you can do
- Create a season (2025/2026, for example).
- Edit it or delete it, if it has no data attached.
Good to know
- It is the first step: without a season you cannot create a championship, and without a championship you cannot import a match into the right context.
