 Nothing is hidden so if `ddbus` doesn't provide something you can simply import `c_lib` and use the pointers

+# Concurrent Updates
+
+If you want to use the DBus connection concurrently with some other features
+or library like a GUI or vibe.d you can do so by placing this code in the update/main loop:
+
+```d
+// initialize Connection conn; somewhere
+// on update:
+if (!conn.tick)
+  return;
+```
+
+Or in vibe.d:
+
+```d
+runTask({
+  import vibe.core.core : yield;
+
+  while (conn.tick)
+    yield(); // Or sleep(1.msecs);
+});
+```
+
 # Todo
 
 `ddbus` should be complete for everyday use but is missing some fanciness that it easily could and should have:
 
-- [vibe.d](http://vibed.org/) event loop compatibility so that calls don't block everything and more importantly, it is possible to write apps that have a DBus server and can do other things concurrently, like a GUI.
 - Marshaling of DBus path and file descriptor objects
 - Better efficiency in some places, particularly the object wrapping allocates tons of delegates for every method.
