 A Discord music bot, written in Kotlin using the kord library.

+
+## Commands
+
+- info -- Show basic infos about the bot
+- play -- Play a song
+- stop -- Stop playing a song and leave the vc
+
+## How to self-host
+
+1. Download the latest release from the Package Registry ("Packages and registries" > "Package Registry")
+   1. It should be called something like this: "Botendo-X.X.X-xxxxxxxx-prod.jar" (replace "X.X.X" with the latest
+      version and xxxxxxxx" with the commit its based on.)
+   2. If you want to run an early version, which may be (very) unsable, you can run a development version. Just use an
+      entry ending in "-dev.jar"
+2. Place it anywhere you want.
+3. Run the following command:
+   > java -jar Botendo-X.X.X-xxxxxxxx-prod.jar
+4. The bot should start and create a config file named "credentials.nils"
+5. Open it and put in your credentials.
+   1. token: your Discord bot token
+   2. lavaip: the IP of your LavaLink instance e.g.: ("ws://192.168.178.1:2333")
+   3. lavapw: your password for the LavaLink instance
+6. Rerun the command
+   > java -jar Botendo-X.X.X-xxxxxxxx-prod.jar
+7. The bot should now be up and running.
+
+## How to set up workspace
+
+Install IntellJ and import the project from git.
+Done.
