+The first time a given issue appears in any board (i.e. the first time a user
+loads a board containing that issue), it will be ordered with 
+respect to other issues in that list according to [Priority order][label-priority].
+At that point, that issue will be assigned a relative order value by the system
+representing its relative order with respect to the other issues in the list. Any time
+you drag-and-drop reorder that issue, its relative order value will change accordingly.
+Also, any time that issue appears in any board when it is loaded by a user,
+the updated relative order value will be used for the ordering. (It's only the first
+time an issue appears that it takes from the Priority order mentioned above.) This means that
+if issue `A` is drag-and-drop reordered to be above issue `B` by any user in
+a given board inside your GitLab instance, any time those two issues are subsequently
+loaded in any board in the same instance (could be a different project board or a different group board, for example), 
+that ordering will be maintained.
