+### Description
+This patch allows you to restart dwl with a keybinding.  
+**NOTE:** that all of your applications are gonna get killed on dwl restart.
+  
+The function creates a file at **/tmp/restart_dwl** and exits dwl.  
+You have to modify your dwl launch script in order for this patch to work.  
+Example dwl launch script:  
+```sh
+do=true
+while $do ||  [ -f /tmp/restart_dwl ]; do
+    do=false
+    rm -rf /tmp/restart_dwl > /dev/null 2>&1
+    dwl
+done
+```
+It's a do-while that checks if **/tmp/restart_dwl** exists after the first run of dwl.  
+If this file exists delete it and start dwl again.
