but you aren't supposed to write these yourself. You should use a browser extension like Get cookies.txt LOCALLY for Chrome or Export Cookies for Firefox instead.

If you want to specify cookie values manually, use a JSON object in your config file:

"cookies": {
    "name1": "value1",
    "name2": "value2",
    "name3": "value3"
}
