-## Timber Logger
+## KAU Logger
 
-[Timber](https://github.com/JakeWharton/timber)'s DebugTree uses the tag to specify the current class that is being logged. 
-To add the tag directly in the message, create an object that extends the TimberLogger class with the tag name as the argument.
-Along with the timber methods (`v`, `i`, `d`, `e`), Timber Logger also supports `eThrow` to wrap a String in a throwable
+`KauLogger` can be extended by an object to implement a logger with a permanent tag.
+It's methods are the same as the main logger, along with the following:
+* Logging methods have two inputs, the main text and private text. 
+If private text is disabled (default), it will not be logged.
+* The loggers have toggles to enable logging as a whole and to filter out priorities that we wish to ignore.
+* Has some other functions, like logging the current thread.
