-  > Be aware that Shake&Tune uses the [Gcode shell command plugin](https://github.com/dw-0/kiauh/blob/master/docs/gcode_shell_command.md) under the hood to call the Python scripts that generate the graphs. While my scripts should be safe, the Gcode shell command plugin also has great potential for abuse if not used carefully for other purposes, since it opens shell access from Klipper.
 
 ## Installation

      ```
   1. Then, append the following to your `printer.cfg` file and restart Klipper (if prefered, you can include only the needed macros: using `*.cfg` is a convenient way to include them all at once):
      ```
+     [shaketune]
      [include K-ShakeTune/*.cfg]
