 The [Mapping module](https://omeka.org/s/modules/Mapping){target=_blank} allows you to geolocate Omeka S items. Maps can also include timelines that allow you to scroll through items on a map in chronological order.
 
-The Mapping module has no global configuration settings. It adds geolocating capabilities to each item, and also adds page blocks to [Site Pages](../sites/site_pages.md) that can be used to display maps for browsing.

 ## CSV Import integration
 
 Mapping is compatible with [CSV Import](../modules/csvimport.md) when importing items (not mixed resources).
 
-If the two modules are enabled, your CSV Import setup will have two new dropdown menus in the "Add mapping" sidebar when you are connecting a spreadsheet column to a property.
+If the two modules are enabled, your CSV Import process will have two new dropdown menus in the "Add mapping" sidebar when you are connecting a spreadsheet column to a property.
 
 The "Resource location" dropdown menu includes three options for pinning the item geographically (latitude, longitude, and latitude/longitude). You can import multiple values for these fields.
 
 The "Default map view" dropdown menu allows you to set a centerpoint and zoom level for the map that displays for that item. Without a map centerpoint, the map will center on the item's pin.
