## Overview

bettermvc is an ASP.NET Core staycation-management web app. Guests can browse property units, while administrators and infodesk staff manage units; the app also includes identity, booking/document/approval domain models, and a PayMongo test-checkout flow. The sampled controllers establish unit browsing and staff CRUD, and the payment controller delegates checkout creation to the PayMongo service. Booking, guest-document, and approval models are represented in the data layer, but no corresponding workflow controllers were shown, so their runtime links are omitted. The README provides no further capability detail.

Main entry points: [`Data/ApplicationDbContext.cs`](https://github.com/uhhhewankowalaakongmaisip/bettermvc/blob/main/Data/ApplicationDbContext.cs) (Persistence context), [`Models/PropertyUnits.cs`](https://github.com/uhhhewankowalaakongmaisip/bettermvc/blob/main/Models/PropertyUnits.cs) (Property units), [`Models/Bookings.cs`](https://github.com/uhhhewankowalaakongmaisip/bettermvc/blob/main/Models/Bookings.cs) (Bookings), [`Services/PayMongoService.cs`](https://github.com/uhhhewankowalaakongmaisip/bettermvc/blob/main/Services/PayMongoService.cs) (Checkout service)
