-Once you've completed the steps to create a new Property, some Installation Instructions will pop up. Select `install manually` where you should see a string that looks like this:
+```ts ins={3} del={2} title="stats.ts"
+//...
+import { getDailyPageViews, getSources } from './providers/plausibleAnalyticsUtils';
+import { getDailyPageViews, getSources } from './providers/googleAnalyticsUtils';
+
+export const calculateDailyStats: DailyStatsJob<never, void> = async (_args, context) => { 
+  //...
+}
