+If you specify a `copy_cmd` in the configuration, it will be used instead of the
+default one. To use the custom command, you need to specify `"filename"` in the
+command, where the image will be saved.

 Once you have it installed, you can use `:checkhealt freeze-code` to see if there
 are any problems with the installation or you need to install additional tools.
