# Managing Layers

The layers of a project are displayed in the **Layers** tab of the project configuration interface. This icon ![](/files/aZ67OT92lngf1iHt8BCo) located in the **Layers** section of the project interface also takes you to the **Layers** tab.

The table shows basic information about each layer of the project. When you click on the name of a layer, a details section displays.&#x20;

In this tab you can define the order of layers in the project. The [Organizing Layers](/e/administrator/jmap-server-administrator-manual/resources-projects/configuring-projects/managing-layers/organizing-layers.md) section offers details on this topic.&#x20;

Buttons allow you to perform management tasks for the layers you select in the table, as well as add new layers to the project.
