+# OrderWeather - Project Completion Report
+
+## 🎯 Mission Accomplished
+
+This document confirms the successful completion of the OrderWeather application as specified in the original problem statement.
+
+## 📋 Original Requirements (Latvian)
+
+> Izveido React + Node.js aplikāciju, kur lietotājs var izvēlēties datumu, pasūtīt "labus laikapstākļus", samaksāt (Stripe/PayPal), un ja OpenWeatherMap.org API prognoze piepildās (nav lietus, temperatūra >20°C), nauda tiek paturēta, ja nē – atgriezta. Izmanto MongoDB, cron job pārbaudei, izveido API struktūru, failu struktūru un GitHub repo.
