 How to use klog
 ===============
-- Replace imports for `github.com/golang/glog` with `k8s.io/klog`
+- Replace imports for `"github.com/golang/glog"` with `"k8s.io/klog/v2"`
 - 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`)
@@ -35,6 +35,10 @@ How to use klog
 
 **NOTE**: please use the newer go versions that support semantic import versioning in modules, ideally go 1.11.4 or greater.
 
+### Coexisting with klog/v2
+
+See [this example](examples/coexist_klog_v1_and_v2/) to see how to coexist with both klog/v1 and klog/v2.
+
 ### 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 synchronize 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`.
