+IPv6 Converter
+=======
+
+The `League\Uri\IPv6\Converter` is a IPv6 Converter.
+
+```php
+<?php
+
+use League\Uri\IPv6\Converter;
+
+echo Converter::expand('[::1]');
+// returns '[0000:0000:0000:0000:0000:0000:0000:0001]'
+echo Converter::compress('[1050:0000:0000:0000:0005:0000:300c:326b]');
+// returns [1050::5:0:300c:326b]
+```
+
+Usage
+--------
+
+The `Converter::compress` method convert an expanded IPv6 host into its compressed form.  
+The method only parameter should represent a host value. The `Converter::exoend` method
+does the opposite.
+
+If you submit a host which is not an IPv6 one then, the submitted host value will be returned
+as is.Conversely, trying to expand an IPv6 host which is already expanded or trying to compress
+an already compressed IPv6 host will return the same value so nothing will be gain performing
+such obvious operation.
+
+```php
+<?php
+
+echo Converter::compress('[::1]'); 
+// returns '[::1]'
+echo Converter::expand('[1050:0000:0000:0000:0005:0000:300c:326b]');
+// returns [1050:0000:0000:0000:0005:0000:300c:326b]
+```
