-### Domain Parts
-
-Purl can parse a URL in to parts and its canonical form. It uses the list of domains from http://publicsuffix.org to break the domain into its public suffix, registerable domain, subdomain and canonical form.
-
-```php
-$url = new \Purl\Url('http://about.jwage.com');
-
-echo $url->publicSuffix; // com
-echo $url->registerableDomain; // jwage.com
-echo $url->subdomain; // about
-echo $url->canonical; // com.jwage.about/
-```
-
-#### Staying Up To Date
-
-The list of domains used to parse a URL into its component parts is updated from time to time.
-To ensure that you have the latest copy of the public suffix list, you can refresh
-the local copy of the list by running `./vendor/bin/pdp-psl data`
-

 You can easily extract urls from a string of text using the `extract` method:
