# Process editor

You use the process editor to create BPMN diagrams. It allows you to visually model your processes using a drag-and-drop mechanism.

## Page overview

The process editor main page is divided into four areas:

* The [menu bar](/workflows/designing-workflows/processes/process-editor-menu-bar.md) on top, just below the navigation bar.
* The [Shape repository](/workflows/designing-workflows/processes/shape-repository.md) on the left side.
* The [canvas](/workflows/designing-workflows/processes/canvas-and-configuration-area.md) in the middle.
* The properties bar on the right side.
