-    "Your GIS becomes much more powerful if it can connect to other GIS and share content with each other. With distributed collaboration, you can connect and integrate your GIS across a network of participant GIS. Your participants could be either ArcGIS Online organizations or ArcGIS Enterprise instances. The benefit of establishing distributed collaboration is to organize, network, and share content between individuals and across organizations and communities.\n",
+    "Your GIS becomes much more powerful if it can connect to other GIS organizations and seamlessly share content. With a [distributed collaboration](https://doc.arcgis.com/en/arcgis-online/administer/understand-collaborations.htm#ESRI_SECTION1_BBEBF7A56A584AA7AF499FA9E318B1C0), you can connect and integrate your GIS across a network of GIS organizational participants. If an ArcGIS Online is to participate, it must serve as a distributed collaboration host, and then any number of ArcGIS Enterprise GIS organizations can be invited to participate. See a comprehensive list of [considerations for creating a distributed collaboration](https://doc.arcgis.com/en/arcgis-online/administer/create-a-collaboration.htm#ESRI_SECTION1_CFEF31FD8C5044CFA88EA9B71ED38C4B) for more details. The benefit of establishing a distributed collaboration is to organize, network, and share content, particularly for ArcGIS Enterprise deployments, between individuals and across organizations and communities.\n",
