+#### Variables for interactive mode:
+
+- `%date`: The current date in the format `YYYY-MM-DD`.
+- `%time`: The current time in the format `HH:MM:SS`.
+- `%datetime`: The current date and time in the format `YYYY-MM-DD HH:MM:SS`.
+- `%counter`: The current counter value.
+- `%usage`: The current usage value.
 
 The defaults can be overridden by providing your own values in the user configuration file,
 named `.chatgpt-cli/config.yaml`, located in your home directory.
