-# FastAPI Application
+# LinkedIn-Based Church Management System
 
-This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
+A comprehensive church management system built with FastAPI that incorporates LinkedIn-style networking features to help church members connect, share updates, and manage events.
+
+## Features
+
+### Authentication & User Management
+- User registration and login with JWT tokens
+- Profile management with bio, position, and contact information
+- User search functionality
+- Profile pictures and personal information
+
+### LinkedIn-Style Networking
+- Send connection requests to other church members
+- Accept/reject connection requests
+- View connections and networking activity
+- Professional-style member profiles
+
+### Social Features
+- Create and share posts (announcements, prayer requests, general updates)
+- Like and comment on posts
+- Community feed with chronological posts
+- Different post types (announcements, prayer requests)
+
+### Event Management
+- Create and manage church events
+- Event registration system with capacity limits
+- Public/private event settings
+- Event attendance tracking

+
+## Tech Stack
+
+- **Backend**: FastAPI (Python)
+- **Database**: SQLite with SQLAlchemy ORM
+- **Authentication**: JWT tokens with bcrypt password hashing
+- **Migrations**: Alembic
+- **Validation**: Pydantic
+- **Code Quality**: Ruff for linting
+
+## Installation & Setup
+
+1. **Clone the repository**
+   ```bash
+   git clone <repository-url>
+   cd linkedinbasedchurchmanagementsystem-7j9m7d
+   ```
+
+2. **Install dependencies**
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+3. **Set up environment variables**
+   Create a `.env` file in the root directory with:
+   ```
+   SECRET_KEY=your-secret-key-here-change-this-in-production
+   ```
+
+4. **Run database migrations**
+   ```bash
+   alembic upgrade head
+   ```
+
+5. **Start the application**
+   ```bash
+   uvicorn main:app --reload
+   ```
+
+The application will be available at `http://localhost:8000`
+
+## API Documentation
+
+Once the server is running, you can access:
+- **Swagger UI**: `http://localhost:8000/docs`
+- **ReDoc**: `http://localhost:8000/redoc`
+- **OpenAPI JSON**: `http://localhost:8000/openapi.json`
+
+## API Endpoints
+
+### Authentication
+- `POST /auth/register` - Register a new user
+- `POST /auth/token` - Login and get access token
+- `GET /auth/me` - Get current user information
+
+### Users
+- `GET /users/` - Get all users (paginated)
+- `GET /users/{user_id}` - Get specific user
+- `PUT /users/me` - Update current user profile
+- `GET /users/search/{query}` - Search users
+
+### Posts
+- `POST /posts/` - Create a new post
+- `GET /posts/` - Get all posts (paginated)
+- `GET /posts/{post_id}` - Get specific post
+- `PUT /posts/{post_id}` - Update post
+- `DELETE /posts/{post_id}` - Delete post
+- `POST /posts/{post_id}/like` - Like a post
+- `DELETE /posts/{post_id}/like` - Unlike a post
+- `POST /posts/{post_id}/comments` - Add comment to post
+- `GET /posts/{post_id}/comments` - Get post comments
+
+### Events
+- `POST /events/` - Create a new event
+- `GET /events/` - Get all events
+- `GET /events/{event_id}` - Get specific event
+- `PUT /events/{event_id}` - Update event
+- `DELETE /events/{event_id}` - Delete event
+- `POST /events/{event_id}/register` - Register for event
+- `DELETE /events/{event_id}/register` - Unregister from event
+- `GET /events/{event_id}/registrations` - Get event registrations
+
+### Connections
+- `POST /connections/` - Send connection request
+- `GET /connections/sent` - Get sent connection requests
+- `GET /connections/received` - Get received connection requests
+- `GET /connections/accepted` - Get accepted connections
+- `PUT /connections/{connection_id}` - Accept/reject connection
+- `DELETE /connections/{connection_id}` - Remove connection
+
+## Environment Variables
+
+The following environment variables need to be set:
+
+- `SECRET_KEY` - JWT secret key for token generation (required)
+- `PORT` - Port number for the application (default: 8000)
+
+## Database
+
+The application uses SQLite as the database, stored at `/app/storage/db/db.sqlite`. The database schema includes:
+
+- **Users**: User accounts with profiles and authentication
+- **Connections**: LinkedIn-style connections between users
+- **Posts**: Social media style posts with likes and comments
+- **Events**: Church events with registration management
+- **Comments**: Comments on posts
+- **Likes**: Like system for posts
+- **Event Registrations**: Event attendance tracking
+
+## Health Check
+
+The application provides a health check endpoint at `/health` that returns the service status and version information.
+
+## Development
+
+### Running with Auto-reload
+```bash
+uvicorn main:app --reload --host 0.0.0.0 --port 8000
+```
+
+### Code Quality
+The project uses Ruff for code formatting and linting:
+```bash
+ruff check .
+ruff format .
+```
+
+### Database Migrations
+To create a new migration:
+```bash
+alembic revision --autogenerate -m "Description of changes"
+```
+
+To apply migrations:
+```bash
+alembic upgrade head
+```
