-# React + TypeScript + Vite
+# NimbusFlow Frontend - Blazor Server Application
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+A modern web application built with .NET 8 Blazor Server for managing member scheduling in the NimbusFlow system.
 
-Currently, two official plugins are available:
+## Features
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+- **Dashboard**: Overview of system statistics and recent activities
+- **Member Management**: Complete CRUD operations for choir members
+- **Schedule Management**: View, accept, decline, and manage member schedules
+- **Service Management**: Create and manage service events
+- **Real-time Updates**: Server-side rendering with SignalR for real-time updates
+- **Responsive Design**: Bootstrap-based UI that works on all devices
 
-## Expanding the ESLint configuration
+## Architecture
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+This Blazor Server application follows a clean architecture pattern:
 
-```js
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
+- **Components/Pages**: Razor components for each major feature
+- **Services**: HTTP client services for backend API communication  
+- **Models**: C# data models matching the Python backend schema
+- **Layout**: Consistent navigation and layout components
 
-      // Remove tseslint.configs.recommended and replace with this
-      ...tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      ...tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      ...tseslint.configs.stylisticTypeChecked,
+## Prerequisites
 
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+- .NET 8.0 SDK
+- Python backend API running on http://localhost:8000/api/
+
+## Getting Started
+
+1. **Restore packages**:
+   ```bash
+   dotnet restore
+   ```
+
+2. **Run the application**:
+   ```bash
+   dotnet watch  # with hot reload
+   # or
+   dotnet run    # without hot reload
+   ```
+
+3. **Access the application**:
+   - HTTPS: https://localhost:5001
+   - HTTP: http://localhost:5000
+
+## API Configuration
+
+The application is configured to communicate with the Python backend API. Update the base URL in `Program.cs` if your backend runs on a different port:
+
+```csharp
+builder.Services.AddHttpClient<IApiService, ApiService>(client =>
+{
+    client.BaseAddress = new Uri("http://localhost:8000/api/");
+});
 ```
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+## Project Structure
 
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
