 # Logging
 
-ReactiveUI comes with its own logging framework which can be used to debug
-your applications as well as ReactiveUI itself. You may ask yourself,
-"Seriously, another logging framework?". The reason RxUI does this itself is
-for portability - none of the common popular logging frameworks support all of
-the platforms that ReactiveUI supports, and many are server-oriented
-frameworks and ill-suited for simple mobile app logging.
-
-### this.Log() and IEnableLogger
-
-ReactiveUI's logger works a bit differently than other frameworks - its
-design is inspired by Rails 'logger'. To use it, make your class implement the
-`IEnableLogger` interface:
-
-```cs
-public class MyClass : IEnableLogger
-{
-    // IEnableLogger doesn't actually require anything of us
-}
-```
-
-Now, you can call the `Log` method on your class. Because of how extension
-methods work, you must prepend `this` to it:
-
-```cs
-this.Log().Info("Downloaded {0} tweets", tweets.Count);
-```
-
-There are **five** levels of logging, `Debug`, `Info`, `Warn`, `Error`, and
-`Fatal`. Additionally, there are special methods to log exceptions - for
-example, `this.Log().InfoException(ex, "Failed to post the message")`.
-
-This trick doesn't work for static methods though, you have to settle for an
-alternate method, `LogHost.Default.Info(...)`.
+ReactiveUI uses [Splat](https://github.com/paulcbetts/splat) for logging and 
+adds some useful helpers for debugging observables to it.

-### Configuring the logger
-
-To configure the logger, register an implementation of `ILogger` (there are
-several built-in ones, such as `DebugLogger`). Here's an example where we use
-a built-in logger, but a custom log level:
-
-```cs
-// I only want to hear about errors
-var logger = new DebugLogger() { LogLevel = LogLevel.Error };
-Locator.CurrentMutable.RegisterConstant(logger, typeof(ILogger));
-```
-
-If you really need to control how things are logged, you can implement
-`IFullLogger`, which will allow you to control every logging overload.
