+# Custom Table Usage Count
+
+This script provides a way of counting where any custom tables (u_) are used in the instance.
+
+Returns JSON object similar to the following:
+
+```json
+[
+   {
+      "name": "u_cmdb_ci_key_value_staging",
+      "label": "Key Value Staging",
+      "references": {
+         "Dictionary": 0,
+         "Variables": 0,
+         "Business Rules": 0,
+         "Client Scripts": 0,
+         "Dictionary Entries": 86,
+         "Dictionary Overrides": 0,
+         "UI Actions": 0,
+         "ACL": 0,
+         "UI Policies": 0,
+         "Data Policy": 0,
+         "Styles": 0,
+         "View Rules": 0,
+         "Workflows": 0,
+         "Flows": 0
+      }
+   }
+]
+```
+
+Easily extended by adding more entries in the USAGE_COUNT_CONFIG object.
+
+```javascript
+const USAGE_COUNT_CONFIG = [
+    { "table": "sys_dictionary", "field": "reference", "title": "Dictionary" },
+    { "table": "item_option_new", "field": "reference", "title": "Variables" },
