+## Configuring Google Cloud Healthcare as a datasource in OHIF
+
+A Google Cloud Healthcare DICOM store can be configured as a DICOMweb datasource
+in OHIF. A full or partial path is permitted in the configuration file. For
+partial paths, the [data source configuration UI](../configuration/dataSources/configuration-ui.md)
+will assist in filling in the missing pieces. For example, a configuration with
+empty `wadoUriRoot`, `qidoRoot` and `wadoRoot` will prompt for the entire path
+step-by-step starting with the project.
