this is a little experiment by me, testing out the Discord.js library.
All you have to do is add an "config.json" file in the "configs" directory. You need to add a string "prefix" which is gonna used as prefix, a string "ownerID" with your discord ID, a string "token" with the private token of your Discord bot to this config.json and a string named "mongo_url" with the url of your mongo database, or simply rename the "example_config.json" to "config.json" and edit the parameters. It could look like this:
{
"token":"YourPrivateToken",
"prefix":"!!",
"userID":"YourDiscordId",
"mongo_url": "mongodb://localhost:27017"
}
