First, let's tie your tasks to their appropriate pre-existing milestone:
Milestones with tasks tied to them have colors that correspond to their statuses:
Green: All tasks tied to the milestone are completed and you're ahead of or on schedule.
Orange: Visual progress tracker with some of the tasks tied to the milestone marked completed.
Red: A reference for being overdue. The milestone end date has concluded with tasks tied to the milestone still not in the Completed list.
Grey: There are no tasks associated to this milestone or no tasks have been completed.
Now task completion is reflected on the associated milestone and automates the visual progress of your milestones! 🎉
