Hi @Pedro César Simões Vilarinho and welcome to the Community!

Done issues have reached the rightmost column of your board. So basically, the issue has reached any status mapped to that column.

Hope this helps!

It means "the team using the board does not need to pay any more attention to this issue", and to make an issue "done", you put it in the last (rightmost) column on the board.
