Instructions for finding Spreadsheet ID
python3 -m pip install -r requirements.txt
gardnr add driver google-sheets google_sheets.driver:GoogleSheets -c spreadsheet_id=<Spreadsheet ID>
To use this driver, you must place a credentials.json file in the same directory as driver.py. See the API client docs for how to create a credentials.json file. Next, you need to execute the driver manually (ex. $ gardnr write -i google-sheets) and follow the instructions to authorize GARDNR.
