 Group surveys and run source gen on each groups:
 Grouping is only run if it is defined in the config (otherwise it use all available surveys).
-
-Example:
-    "Groups" : {
-                "PROD" : ["ODK-server", "kobo-server", "CSV-CAM"],
-                "WRT" : ["ODK", "CSV"]
-            } 
-
-It is based on the 'Origin' column of the surveys.
-All unique 'Origin' will create its own group alongside the ones defined in the config.
-Groups can be ignored by defining 'GroupsToIgnore' in the config (this has no effect on 'Origin' types).
-
+Groups need to have a name, a key to at least one column and a list of unique elements in that column to group by.
 Example:
-    "GroupsToIgnore" : ["ODK-server", "kobo-server", "CSV-CAM", "ODK", "CSV", "PV"]
+        "Groups" : {
+            "PROD" : {
+                "Origin" : ["CSV_01", "CSV_02", "ODK_01", "ODK_02"],
+                "PublishedLevel" : ["Unpubl", "Publ", "Unknown"]
+            },
+            "WRT-Publ" : {
+                "Origin" : ["CSV_01", "CSV_02", "ODK_01", "ODK_02"],
+                "PublishedLevel" : ["Publ"]
+            }
+        },
+        "GroupBy" : ["Origin", "PublishedLevel"],
+        "GroupsToIgnore" : ["CSV_01", "CSV_02", "ODK_01", "ODK_02", "Unpubl", "Publ"], 
+
+Alongside the defined groups, individual groups get created based on the unique elements in the columns defined in "GroupBy".
+Groups can be ignored by defining "GroupsToIgnore" in the config.
