 1 | # Discord Bot V2
 2 | 
 3 | ## Description
 4 | This is a simple Discord bot I made for fun in Java. It is currently used on KG's Discord server. It offers an easy way to create commands along with options like a cool down and the ability to execute a custom function. Everything is handled in an XML config file. You may specify the path to the config file via command-line (argument #1).
 5 | 
 6 | ## JAR File
 7 | There is currently no JAR file included. I've built one on my own, but since the Discord API token is hard-coded into the project, I cannot provide a JAR file. Feel free to use my project and compile your own JAR file.
 8 | 
 9 | ## To Do
10 | * Have the Discord API token be handled in the config file.
11 | * Once the above task is done, include a JAR file.
12 | * Optimizations + better support.
13 | * Add custom functions.
14 | 
15 | ## Run In Java Via JAR
16 | Here is the command line I use for my Linux server:
17 | 
18 | ```
19 | /usr/bin/java -jar /home/roy/my-discord-bot.jar "/etc/discordbot/config.xml"
20 | ```
21 | 
22 | The config file is located at `/etc/discordbot/config.xml` in this case.
23 | 
24 | ## Credits
25 | * [Christian Deacon](https://www.linkedin.com/in/christian-deacon-902042186/) - Creator.
