+### Providing Country Headers
+
+If your deployed app has header with user country in ISO 3166-1 alpha-2 format, you can specify this header, so country will be taken from it: 
+
+```ts
+plugins: [
+      new AuditLogPlugin({
+        //diff-add
+        isoCountryCodeRequestHeader: 'CF-IPCountry',
+        resourceColumns: {

+          resourceActionColumnName: 'action',
+          resourceDataColumnName: 'diff',
