+How to use klog
+===============
+- Replace imports for `github.com/golang/glog` with `k8s.io/klog`
+- Use `klog.InitFlags(nil)` explicitly for initializing global flags as we no longer use `init()` method to register the flags
+- You can now use `log-file` instead of `log-dir` for logging to a single file (See `examples/log_file/usage_log_file.go`)
+- If you want to redirect everything logged using klog somewhere else (say syslog!), you can use `klog.SetOutput()` method and supply a `io.Writer`. (See `examples/set_output/usage_set_output.go`)
+- For more logging conventions (See [Logging Conventions](https://github.com/kubernetes/community/blob/master/contributors/devel/logging.md))
+
+### Coexisting with glog
+This package can be used side by side with glog. [This example](examples/coexist_glog/coexist_glog.go) shows how to initialize and syncronize flags from the global `flag.CommandLine` FlagSet. In addition, the example makes use of stderr as combined output by setting `alsologtostderr` (or `logtostderr`) to `true`.
