-      As long as :mod:`philo.urls` is included somewhere in the urlpatterns, this will return the URL of this node. The returned value will always start and end with a slash.
+      This is essentially a shortcut for calling :meth:`construct_url` without a subpath - which will return the URL of the Node.
+
+   .. method:: construct_url([subpath="/", request=None, with_domain=False, secure=False])
+
+      This method will do its best to construct a URL based on the Node's location. If with_domain is True, that URL will include a domain and a protocol; if secure is True as well, the protocol will be https. The request will be used to construct a domain in cases where a call to :meth:`Site.objects.get_current` fails.
+
+      Node urls will not contain a trailing slash unless a subpath is provided which ends with a trailing slash. Subpaths are expected to begin with a slash, as if returned by :func:`django.core.urlresolvers.reverse`.
+
+      :meth:`construct_url` may raise the following exceptions:
+
+      - :class:`NoReverseMatch` if "philo-root" is not reversable -- for example, if :mod:`philo.urls` is not included anywhere in your urlpatterns.
+      - :class:`Site.DoesNotExist <ObjectDoesNotExist>` if with_domain is True but no :class:`Site` or :class:`RequestSite` can be built.
+      - :class:`AncestorDoesNotExist` if the root node of the site isn't an ancestor of the node constructing the URL.
