## Installation and usage

Create a Discord bot here: https://discordapp.com/developers/applications/me

Then, add the bot to your Discord server using the following link, replace the Client ID with that of your bot.
```
https://discordapp.com/oauth2/authorize?client_id=<CLIENT ID>&scope=bot
```

In your Minecraft server.properties, make sure you have the following and restart the server:
```
enable-rcon=true
rcon.password=<your password>
rcon.port=<1-65535>
```

Clone repository onto a server, edit ```config.json``` (see below for more info) and change any options, and then, in the repository folder:
```sh
$ yarn
$ yarn start
```

If you are running this locally, check the `IS_LOCAL_FILE` flag and related options below. Otherwise, perform the following command: 
On your server hosting (in a screen/tmux session or background process, make sure to replace your `YOUR_URL` with whatever URL you're using (`localhost:8000` if running on the same server and default config) and `PATH_TO_MINECRAFT_SERVER_INSTALL` with the path to the Minecraft server installation, such as `/usr/home/minecraft_server/`):

``` sh
tail -F /PATH_TO_MINECRAFT_SERVER_INSTALL/logs/latest.log | grep --line-buffered ": <" | while read x ; do echo -ne $x | curl -X POST -d @- http://YOUR_URL/minecraft/hook ; done
```

You can also easily Deploy to Heroku and the like, just be sure to edit `YOUR_URL` in the command to match accordingly.
