For testing, create a file data/config.json and set it to this:
{
"token": "",
"server_id": "",
"staff_role_id": "",
"dev_role_id": "",
"bot_name": "",
"support_channel": "",
"invalid_tag_id": "",
"open_tag_id": "",
"resolved_tag_id": "",
"to_do_tag_id": "",
"tag_prefix": ""
}Then of course fill out the entries to your values. Everything has to be set otherwise it won't work.
