## Project Overview

This API provides endpoints to manage superheroes, their superpowers, and the relationships between them. You can create, read, update, and delete heroes and powers, as well as associate heroes with specific powers.

## Getting Started

### Prerequisites

Before you begin, make sure you have the following installed on your system:

- [Ruby](https://www.ruby-lang.org/en/documentation/installation/)
- [Ruby on Rails](https://rubyonrails.org/)
- [Git](https://git-scm.com/)

### Project Setup

1. Clone the repository:

   ```bash
   git clone <repository-url>
   cd SuperheroAPI
  1. Install project dependencies:

    bundle install
  2. Create the database and run migrations:

    rails db:create
    rails db:migrate

Database Initialization (Optional)

If you want to seed the database with sample data for testing, run:

rails db:seed

Running the Server

To start the API server, run:

rails server

The API will be accessible at http://localhost:3000.
