 Whilst you could try to set up constraints covering all the public holidays in
 your country, it's probably easier to just retrieve them from a remote source.
 
-BusinessTime supports this for WebCal.fi out of the box.
-
-### WebCal.fi
-
-WebCal.fi is easy to use as its data is provided publicly without any
-authentication. You do need to include the
-[Guzzle](https://github.com/guzzle/guzzle) library in your project to use this,
-though.
-
-```php
-$factory = new BusinessTime\Remote\WebCalFiFactory(
-    new GuzzleHttp\Client(),
-    'https://www.webcal.fi/cal.php?id=83&format=json' // for example
-);
-$dates = $factory->getDates();
-// = array of date objects from the specified calendar.
-$webCalFiConstraint = $factory->makeConstraint();
-// = a constraint containing the retrieved dates and their descriptions.
-```
-
-The constraint will be set up with names and dates from the WebCal.fi calendar
-you specify.
-
-You can find WebCal.fi calendars to suit your needs at e.g.
-https://www.webcal.fi/en-GB/other_file_formats.php
-
-Note that you can also use the `except()` method on the WebCalFi constraint to
-add customised exceptions to the dates it provides.
-
 ### Custom remote sources
 
 You can add any other source you like by implementing the `Constraint` interface
