+wait-group
+==========
+
+Wait group provides a way to block while waiting for jobs to finish. It’s
+designed to mimic Go’s [sync.WaitGroup] in Common Lisp.
+
+
+## Example
+The following initialises a WebSocket client, sends a message, and waits for a
+response.
+
+``` common-lisp
+(defvar *client* (wsd:make-client "ws://localhost:5555/"))
+(defvar *wg* (wait-group:make-wait-group))
+
+(wsd:start-connection *client*)
+
+(wsd:on :message *client* #'(lambda (message)
+                              (format t "Received: ~a~%" message)
+                              (wait-group:done *wg*))
+
+(wsd:send *client* "Sending")
+(wait-group:add *wg*)
+
+(wait-group:wait *wg*)
+
+(wsd:close-connection *client*)
+```
+
+
+## Install
