-# Pipeline Schedules
-
-> **Note**:
-- This feature was introduced in 9.1 as [Trigger Schedule][ce-105533]
-- In 9.2, the feature was [renamed to Pipeline Schedule][ce-10853]
-
-Pipeline schedules can be used to run pipelines only once, or for example every
-month on the 22nd for a certain branch.
-
-## Using Pipeline Schedules
-
-In order to schedule pipelines, navigate to your their pages **Pipelines ➔ Schedules**
-and click the **New Schedule** button.
-
-![New Schedule Form](img/pipeline_schedules_new_form.png)
-
-After entering the form, hit **Save Schedule** for the changes to have effect.
-You can check a next execution date of the scheduled trigger, which is automatically calculated by a server.
-
-## Taking ownership
-
-![Schedules list](img/pipeline_schedules_list.png)
-
-Pipelines are executed as a user, which owns a schedule. This influences what
-projects and other resources the pipeline has access to. If a user does not own
-a pipeline, you can take ownership by clicking the **Take ownership** button.
-The next time a pipeline is scheduled, your credentials will be used.
-
-> **Notes**:
-- Those pipelines won't be executed precicely. Because schedules are handled by
-Sidekiq, which runs according to its interval. For exmaple, if you set a schedule to
-create a pipeline every minute (`* * * * *`) and the Sidekiq worker performs 00:00
-and 12:00 o'clock every day (`0 */12 * * *`), only 2 pipelines will be created per day.
-To change the Sidekiq worker's frequency, you have to edit the `trigger_schedule_worker_cron`
-value in your `gitlab.rb` and restart GitLab. The Sidekiq worker's configuration
-on GiLab.com is able to be looked up at [here](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/gitlab.yml.example#L185).
-- Cron notation is parsed by [Rufus-Scheduler](https://github.com/jmettraux/rufus-scheduler).
-- When the owner of the schedule does not have the ability to create pipelines
-anymore, due to e.g. being blocked or removed from the project, the schedule is
-deactivated. Another user can take ownership and activate it, so the schedule is
-run again.
