The Currencies Bundle adds a currency widget to Contao

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require craffft/currencies-bundle "dev-master"

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Then, enable the bundle by adding it to the list of registered bundles in the app/AppKernel.php file of your project:

<?php
// app/AppKernel.php

// ...
class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            // ...

            new Craffft\CurrenciesBundle\CraffftCurrenciesBundle(),
        );

        // ...
    }

    // ...
}
