    "Quantify allows for serialization of :class:`~quantify_scheduler.QuantumDevice`, :class:`~quantify_scheduler.DeviceElement` (e.g. :class:`~quantify_scheduler.BasicTransmonElement`) and :class:`~quantify_scheduler.Schedule` objects to json strings and json files. Each class has the following methods:\n",
    "\n",
    "- `to_json` : Converts the object into a json string.\n",
    "- `from_json` : Converts a json string back into the object.\n",
    "- `to_json_file` : Stores the json string to a file.\n",
    "- `from_json_file` : Reads the json string from a file and converts it back into the object.\n",
