+## Small library to generate unique private mac addresses
+
+### Usage
+```php
+use Sikofitt\GenerateMac\Mac;
+
+$mac = new Mac(); // default is ':'
+$address = $mac->getAddress(); // ab:cd:ef:01:23:45
+
+$mac = new Mac('-');
+$address = $mac->getAddress(); // ab-cd-ef-01-23-45
+
+$mac = new Mac('');
+$address = $mac->getAddress(); // abcdef012345
+```
+
+If you don't care that it is unique you can remove the check for private mac prefixes.
+
+```php
+    $mac = new Mac(':', false);
+    $address = $mac->getAddress();
+
+    // '52:54:00:ab:cd:ef',  QEMU virtual NIC prefix 52:54:00
+    // It's really not likely there will be a collision though.
+```
+
+Generate multiple mac addresses
+```php
+$addresses = $mac->getAddresses(10);
+
+var_dump($addresses);
+/*
+ *   array (
+ *       0 => '8a:20:0b:b7:c4:62',
+ *       1 => '56:7d:47:56:e8:bd',
+ *       2 => '2a:ae:7b:44:6f:9d',
+ *       3 => '6a:36:1a:7c:04:3a',
+ *       4 => '3a:3d:93:f5:a6:12',
+ *       5 => '8a:85:ce:11:2c:a2',
+ *       6 => '06:54:6f:b1:11:48',
+ *       7 => 'c6:fe:9d:86:38:dd',
+ *       8 => 'ba:39:b3:a2:a1:fa',
+ *       9 => '32:73:c0:b3:62:27',
+ *   );
+ */
