+# Mixlib::Log
+
+[![Build Status Master](https://travis-ci.org/chef/mixlib-log.svg?branch=master)](https://travis-ci.org/chef/mixlib-log) [![Gem Version](https://badge.fury.io/rb/mixlib-log.svg)](https://badge.fury.io/rb/mixlib-log)
+
+Mixlib::Log provides a mixin for enabling a class based logger object, a-la Merb, Chef, and Nanite. To use it:
+
+```ruby
+require 'mixlib/log'
+
+class Log
+  extend Mixlib::Log
+end
+```
+
+You can then do:
+
+```ruby
+Log.debug('foo')
+Log.info('bar')
+Log.warn('baz')
+Log.error('baz')
+Log.fatal('wewt')
+```
+
+By default, `Mixlib::Logger` logs to STDOUT. To alter this, you should call +Log.init+, passing any arguments to the standard Ruby Logger. For example:
+
+```ruby
+Log.init('/tmp/logfile')  # log to /tmp/logfile   
+Log.init('/tmp/logfile', 7)  # log to /tmp/logfile, rotate every day
+```
+
+Enjoy!
