+ my $token = ...; # API token here
+ my $sw = WebService::Scaleway->new($token);
+ my $org = $sw->organizations;
+
+ # Create an IP, a volume, and use them for a new Debian Jessie server

+ # Change the server name

+
+=head1 DESCRIPTION
+
+Scaleway is an IaaS provider that offers bare metal ARM cloud servers.
+WebService::Scaleway is a Perl interface to the Scaleway API.
+
+=head2 Constructors
+
+WebService::Scaleway objects are defined by their authentication
+token. There are two consructors:
+
+=over
+
+=item WebService::Scaleway->B<new>(I<$auth_token>)
+
+Construct a WebService::Scaleway object from a given authentication
+token.
+
+=item WebService::Scaleway->B<new>(I<$email>, I<$password>)
+
+Construct a WebService::Scaleway object from an authentication token
+obtained by logging in with the given credentials.
+
+=back
+
+=head2 Listing resources
+
+These methods return a list of all resources of a given type
+associated to your account. Each resource is a blessed hashref with
+C<AUTOLOAD>ed accessors (for example C<< $resource->{name} >> can be
+written as C<< $resource->name >>) and that stringifies to the ID of
+the resource: C<< $resource->id >>.
+
+There is no difference between B<resources>() and
+B<list_resources>().

+=head2 Modifying resources
+
+These methods take a hashref representing a resource that already
+exists and update it. The value of C<< $resource->{id} >> is used for
+identifying this resource on the remote end. Both blessed and
+unblessed hashrefs are accepted. The updated resource is returned as a
+blessed hashref as described in L</"Listing resources">.

+
+=head2 Creating resources
+
+These methods take either a hash that is passed directly to the API or
+a method-specific list of positional parameters. They create a new
+resource and return it as a blessed hashref as described in
+L</"Listing resources">.
+
+When using positional parameters, you can pass a resource in blessed
+hashref format where a resource ID is expected. The function will call
+C<< ->id >> on the resouce automatically.
+
+Most of these methods require an organization ID. You can obtain it
+with the B<organizations> method described above.
+
+=over
+
+=item $self->B<create_token>(I<\%data>)
+
+=item $self->B<create_token>(I<$email>, I<$password>, [I<$expires>])
+
+Authenticates a user against their username and password and returns
+an authentication token. If I<$expires> (default: false) is true, the
+token will expire.
+
+This method is called internally by the two-argument constructor.
+
+Official documentation: L<https://developer.scaleway.com/#tokens-tokens-get>.
+
+=item $self->B<create_server>(I<\%data>)
+
+=item $self->B<create_server>(I<$name>, I<$organization>, I<$image>, I<$volumes>, [I<$tags>])
+
+Creates and returns a new server.
+
+I<$name> is the server name. I<$organization> is the organization ID.
+I<$image> is the image ID. I<$volumes> is a "sparse array" (hashref
+from indexes to volumes, indexed from 1) of volumes. I<$tags> is an
+optional arrayref of tags.
+
+Note that the volumes must be unblessed hashrefs. If I<$vol> is a
+volume, you can use this idiom: C<< $volumes = {1 => {%$vol}} >>.
+
+Official documentation: L<https://developer.scaleway.com/#servers-servers-get>.
+
+=item $self->B<create_volume>(I<\%data>)
+
+=item $self->B<create_volume>(I<$name>, I<$organization>, I<$volume_type>, I<$size>)
+
+Creates and returns a new volume. I<$volume_type> currently must be
+C<l_ssd>. I<$size> is the size in bytes.
+
+Official documentation: L<https://developer.scaleway.com/#volumes-volumes-get>.
+
+=item $self->B<create_snapshot>(I<\%data>)
+
+=item $self->B<create_snapshot>(I<$name>, I<$organization>, I<$volume_id>)
+
+Creates and returns a snapshot of the volume I<$volume_id>.

+
+=item $self->B<create_image>(I<\%data>)
+
+=item $self->B<create_image>(I<$name>, I<$organization>, I<$root_volume>, I<$arch>)
+
+Creates and returns an image from the volume I<$root_volume>. I<$arch>
+is the architecture of the image (currently must be C<"arm">).

+=head2 Miscellaneous methods
+
+These are methods that don't fit any previous category. Any use of
+"blessed hashref" refers to the concept described in L</"Listing
+resources">. Wherever a resource ID is expected, you can instead pass
+a resource as a blessed hashref and the method will call C<< ->id >>
+on it for you.
+
+=over
+
+=item $self->B<server_actions>(I<$server_id>)
+
+=item $self->B<list_server_actions>(I<$server_id>)
+
+Returns a list of strings representing possible actions you can
+perform on the given server. Example actions are powering on/off a
+server or rebooting it.
+
+Official documentation: L<https://developer.scaleway.com/#servers-actions-get>
+
+=item $self->B<perform_server_action>(I<$server_id>, I<$action>)
+
+Performs an action on a server. I<$action> is one of the strings
+returned by B<server_actions>. The function returns a blessed hashref
+with information about the task.
+
+This is not very useful, as this module does not currently offer any
+function for tracking tasks.
+
+Official documentation: L<https://developer.scaleway.com/#servers-actions-post>
+
+=item $self->B<refresh_token>(I<$token_id>)
+
+This method takes the ID of an expirable token, extends its expiration
+date by 30 minutes, and returns the new token as a blessed hashref.
+
+Official documentation: L<https://developer.scaleway.com/#tokens-token-patch>
+
+=item $self->B<server_metadata>
+
+This method can only be called from a Scaleway server. It returns
+information about the server as a blessed hashref.
