+You can remove an empty directory using the `DELETE` verb and the `dir=true` parameter. Following will succeed because `/dir` was empty
 
 ```sh
-curl -L 'http://127.0.0.1:4001/v2/keys/foo_dir?dir=true' -XDELETE
+curl -L 'http://127.0.0.1:4001/v2/keys/dir?dir=true' -XDELETE

 ```json
 {
     "action": "delete",
     "node": {
