## Overview

MyFi is an in-progress personal-finance web app. Users enter through the root route, reach the landing page or authenticated dashboard, and can work with budgets; the documented domain includes categories and expenses, with reusable budget templates. Identity provides account and role management, while the EF Core context stores finance and identity data. The graph reflects sampled routing, budget listing, and Identity setup; create/template pages and several advertised capabilities are represented only where the tree or README supports them. AI and gamification are planned, not implemented in the sampled runtime.

Main entry points: [`MyFi/Program.cs`](https://github.com/ab0213ab/myfi/blob/master/MyFi/Program.cs) (App routing), [`MyFi/Data/MyFiDbContext.cs`](https://github.com/ab0213ab/myfi/blob/master/MyFi/Data/MyFiDbContext.cs) (EF data context), [`MyFi/Pages/Budgets/CreateFromTemplate.cshtml.cs`](https://github.com/ab0213ab/myfi/blob/master/MyFi/Pages/Budgets/CreateFromTemplate.cshtml.cs) (Create from template), [`MyFi/Models/Budget.cs`](https://github.com/ab0213ab/myfi/blob/master/MyFi/Models/Budget.cs) (Budgets)
