 JDA currently provides a fallback Logger in case that no SLF4J implementation is present.
 We strongly recommend to use one though, as that can improve speed and allows you to customize the Logger as well as log to files

 ### Annotations
 
 We use a number of annotations to indicate future plans for implemented functionality such as new features of
 the Discord API.
