+## Get new address
+```php
+    $client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');

+## Make a new Payment
+```php
+    $client = new \Electrum\Client('http://127.0.0.1', 7777, 0, 'user', 'password');
+    $method = new \Electrum\Request\Method\Payment\PayTo($client);
+    $method->setDestination('BTC4ddress1234'); //Destination parameter is the address where we'll send the btc
+    $method->setAmount(1); //send 1 BTC = 10k usd
+    
+    $tx = $method->execute(); //$tx returns the transaction ID of the payment, this is still not sent to the blockchain
+    /**
+    * @param array ['password' => '<password>']
+    * If the Electrum wallet is encrypted with a password use the following execute method instead
+    * The previous one will return an error of "Password required"
+    */
+    //$tx = $method->execute(['password' => 'myPass123']); //
+    
+    $broadcast = new Electrum\Request\Method\Payment\Broadcast($client);
+    $broadcast->setTransaction($tx);
+    $result = $broadcast->execute(); //broadcasts payment to the blockchain
+    echo $result;
+    
+    A payment has been made
+

 ## Custom Client Configuration
 Every Request/Method takes a `Electrum\Client`-instance as parameter which replaces the default one. A custom instance can be usefull if you want to set custom config params like another Hostname or Port.
