+## Special milestone filters
+
+In addition to the milestones that exist in the project or group, there are some
+special options available when filtering by milestone:
+
+* **No Milestone** - only show issues or merge requests without a milestone.
+* **Upcoming** - show issues or merge request that belong to the next open
+  milestone with a due date, by project. (For example: if project A has
+  milestone v1 due in three days, and project B has milestone v2 due in a week,
+  then this will show issues or merge requests from milestone v1 in project A
+  and milestone v2 in project B.)
+* **Started** - show issues or merge requests from any milestone with a start
+  date less than today. Note that this can return results from several
+  milestones in the same project.
