+# autowhitelist
+
+This ts project automatically whitelists people to a minecraft server from a discord. It's very very simple.
+Supports multiple users in one message, e.g "USERONE", "USERTWO". This isn't configurable, but quite easy to remove.
+
+All whitelists can also be removed by just deleting the message, helping both users incase username changes or other issues, and staff. 
+
+Run `bun i`, copy `config.example.json` to `config.json` and change all of the settings. The channel option is the channel ID, which you can copy by using developer mode on discord. Then, just start the bot.
+If you get something as such from the bot, then everything's done right:
+```
+RCON connected.
+RCON authenicated.
+Ready! Logged in as Slop Bridge#2702
+```
+
+There is also an option to get rid of nicknames changes. Set "changeNicknames" to "false".
+This project was created using `bun init` in bun v1.1.13. [Bun](https://bun.sh) is a fast all-in-one JavaScript runtime.
