Milestones are the columns that run along the top of the Flow Builder Canvas. Milestones are added by dragging the Milestone Step into the Flow Builder.

1. This Flow is broken down in to 2 milestones called Phase 1 and Phase 2. Steps are placed in the appropriate column for each milestone. You can add as many Milestones as needed to break down your Flow in to manageable areas.
2. Use the blue arrows to move a particular milestone to the left or right using the corresponding button.
3. The Red X will remove a Milestone from your Flow.
4. A Duration can be set for each Milestone for planning purposes.
