+# Automatic and manual scheduling mode
+
+<div class="glossary">
+
+The **Gantt chart** in OpenProject displays the work packages in a timeline. To schedule the work packages there is a automatic schduling mode (default) and a manual scheduling mode (new in release 11.0). To add relations between work packages you can set them as predecessor or follower.

+
+## Create a new element in the Gantt chart
+
+To add a work package (e.g. phase, milestone or task) to a Gantt chart, click the **+ Create new work package** link at the bottom of the work package list view.
+
+You can add a subject and make changes to type, status or more fields.
+
+In the **Gantt chart** you can schedule the work package with drag and drop and change the duration.
+
+### How to change the order of an item in the Gantt chart?

+
+### How to change the duration of an element in the Gantt chart?
+
+To change the duration of a phase in the Gantt chart view, click on the element in the Gantt chart. You can change the duration with drag and drop, shorten or prolong the duration and change start and due date.
+
+## Relations in the Gantt chart
+
+In the Gantt chart you can track dependencies of work packages (e.g. phases, milestones, tasks). This way you can get an easy overview of what needs to be done in which order, e.g. what tasks need to be completed to achieve a milestone.
+
+To add a dependency make right mouse click on an element in the Gantt chart.
+
+In the menu, choose **Add predecessor** or **Add follower**.
+
+Select the item which you want to create the dependency with. The precede and follow relation is marked with a small blue line in the Gantt chart.
+
+OpenProject does not yet include a baseline feature to compare scheduled versions. However, we are aware of the need for it and documented it. Please check [here](https://community.openproject.com/projects/openproject/work_packages/26448/activity) for an update.

+
+## Gantt chart configuration
+
+To open the Gantt chart configuration, please open the **settings** icon with the three dots on the top right of the work package module.
+Choose **Configure view ...** and select the tab **Gantt chart**.
+
+Here you can **adapt the Zoom level**, or choose and Auto zoom which will select a Zoom level which best fits to your browser size to have optimal results on a page.

Just select which additional information you would need to have in the Gantt chart. This can be especially relevant if you want to print your Gantt chart.
