+### Scheduled status
+
+Allows users to schedule a toot (with media attachments) to be published at a certain future date.
+
+The scheduled date must be at least 5 minutes into the future. At most, 300 toots can be scheduled at the same time. Only 50 toots can be scheduled for any given day.
+
+When `scheduled_at` option is present, instead of creating a status, we only run status validation, and if it passes, we create an entry in scheduled_statuses which encodes the status attributes.  Every 5 minutes, a scheduler iterates over the scheduled_statuses table to fetch the ones due in the next 5 minutes, and push them into a more precise Sidekiq queue. In Sidekiq, the individual statuses are created, with media attachments being unassigned from the scheduled status and assigned to the real one.
+
+This option was added since v2.7.0.

 ## DELETE /api/v1/statuses/:id
 
 Remove a status. The status may still be available a short while after the call.
