 ```
 
+If you want to add argument to your shell command, you can use the query arguments.
+```
+  - name: "Delete-a-specific-file"
+    signals:
+      - order: "remove file {{ query }}"
+    neurons:
+      - shell:
+          cmd: "rm "
+          file_template: remove_file.j2
+          args:
+              - query
+```
+In the example above, kalliope will remove the file you asked for in the query.
+eg: "remove file test", the executed command will be "rm test"
+
 ## Templates example 
 
 Template `remove_file.j2` used in the remove file example remove_file.j2
