+The `workspace/configuration` request is sent from the server to the client to
+fetch configuration settings from the client. The request can fetch several
+configuration settings in one roundtrip. The order of the returned configuration
+settings correspond to the order of the passed `ConfigurationItems` (e.g. the
+first item in the response is the result for the first configuration item in
+the params).
+
+A `ConfigurationItem` consists of the configuration section to ask for and an
+additional scope URI. The configuration section asked for is defined by the
+server and doesn't necessarily need to correspond to the configuration store
+used by the client. So a server might ask for a configuration
+`cpp.formatterOptions` but the client stores the configuration in an XML store
+layout differently. It is up to the client to do the necessary conversion. If a
+scope URI is provided the client should return the setting scoped to the
+provided resource. If the client for example uses EditorConfig to manage its
+settings the configuration should be returned for the passed resource URI. If
+the client can't provide a configuration setting for a given scope then `null`
+needs to be present in the returned array.
+
+This pull model replaces the old push model were the client signaled
+configuration change via an event. If the server still needs to react to
+configuration changes (since the server caches the result of
+`workspace/configuration` requests) the server should register for an empty
+configuration change using the following registration pattern:
+
+```julia
+connection.client.register(DidChangeConfigurationNotification.type, undefined)
+```
