 The above example creates a bot that responds "Hello world!" to `!hello`.
 
 Extending the configuration is possible by creating an `application.conf` HOCON file. By default, Koncorda uses what
 is defined in [reference.conf](koncorda/src/main/resources/reference.conf), but this can be overridden.
 
 ```hocon
 koncorda {
-  // The Discord bot token, comes from the environmental variable DISCORD_TOKEN
-  discord-token = ${DISCORD_TOKEN}
-  // The command prefix, defaults to ! or the environmental variable COMMAND_PREFIX
-  command-prefix = "!"
-  command-prefix = ${?COMMAND_PREFIX}
+  command-prefix = "/"
 }
 
 your-bot {
-    some-option = "some value"
+  some-option = "some value"
 }
