+Porter Quick Start Guide for Symfony
+====================================
+
+This quick start guide will walk through integrating Porter into a new Symfony project from scratch and assumes you already have a PHP environment set up with Composer. Let's start by initializing our Composer file by running `composer init` in our project's root directory and accepting the defaults. We can skip defining dependencies interactively because we'll issue separate commands in a moment.
+
+Let's start with the [European Central Bank][ECB provider] (ECB) provider by including it in our `composer.json` with the following command.
+
+```sh
+composer require provider/european-central-bank
+```
+
+We now have the provider installed along with all its dependencies, including Porter herself. We want to create a `new Porter` instance now, but we need to pass a `ContainerInterface` to her constructor. Any PSR-11 container is valid, but let's use Joomla DI for now.
+
+```sh
+composer require joomla/di
+```
+
+Create a new container and register an instance of `EuropeanCentralBankProvider` with it. Pass the container to a new Porter instance. Don't forget to include the autoloader!
+
+```php
+use Joomla\DI\Container;
+use ScriptFUSION\Porter\Porter;
+use ScriptFUSION\Porter\Provider\EuropeanCentralBank\Provider\EuropeanCentralBankProvider;
+
+require 'vendor/autoload.php';
+
+$container = new Container;
+$container->set(EuropeanCentralBankProvider::class, new EuropeanCentralBankProvider);
+
+$porter = new Porter($container);
+```
+
+We're now ready to import any of the ECB's resources. Let's import the latest daily foreign exchange rates provided by `DailyForexRates`. Porter's `import()` method requires a `Import` that accepts the resource we want to import.
+
+```php
+use ScriptFUSION\Porter\Import\Import;
+use ScriptFUSION\Porter\Provider\EuropeanCentralBank\Provider\Resource\DailyForexRates;
+
+$rates = $porter->import(new Import(new DailyForexRates));
+```
+
+Porter returns an iterator, so we can now loop over the rates and print them out.
+
+```php
+foreach ($rates as $rate) {
+    echo "$rate[currency]: $rate[rate]\n";
+}
+```
+
+This outputs something similar to the following, with today's current rates.
+
+>USD: 1.2304  
+JPY: 131.66  
+BGN: 1.9558  
+CZK: 25.357  
+DKK: 7.4469  
+...
+
+Since these rates come from the European Central Bank, they're relative to the Euro (EUR), which is assumed to always be *1*. We can use this information to write a currency converter that's always up-to-date with the latest exchange rate information.
+
+This just scratches the surface of Porter without going into any details. Explore the [rest of the manual][Readme] at your leisure to gain a fuller understanding of the features at your disposal.
