+cyclewindows
+============
+
+Description
+-----------
+
+The **CycleWindows** patch for the Dynamic Window Manager (dwm) introduces
+a powerful way to streamline your workflow. By allowing you to cycle
+through all open windows of the same program with simple key combinations
+MOD+n, and MOD+Shift+n.
+
+This patch is inspired by a Reddit post [this post](https://www.reddit.com/r/suckless/comments/1dnfs74/comment/la36x4l/).
