-# Contributing
-
-## Issues
-
-* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
-* Please indicate the platform you are using fsnotify on.
-* A code example to reproduce the problem is appreciated.
-
-## Pull Requests
-
-### Contributor License Agreement
-
-fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
-
-Please indicate that you have signed the CLA in your pull request.
-
-### How fsnotify is Developed
-
-* Development is done on feature branches.
-* Tests are run on BSD, Linux, OS X and Windows.
-* Pull requests are reviewed and [applied to master][am] using [hub][].
-  * Maintainers may modify or squash commits rather than asking contributors to.
-* To issue a new release, the maintainers will:
-  * Update the CHANGELOG
-  * Tag a version, which will become available through gopkg.in.
- 
-### How to Fork
-
-For smooth sailing, always use the original import path. Installing with `go get` makes this easy. 
-
-1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
-2. Create your feature branch (`git checkout -b my-new-feature`)
-3. Ensure everything works and the tests pass (see below)
-4. Commit your changes (`git commit -am 'Add some feature'`)
-
-Contribute upstream:
-
-1. Fork fsnotify on GitHub
-2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
-3. Push to the branch (`git push fork my-new-feature`)
-4. Create a new Pull Request on GitHub
-
-This workflow is [thoroughly explained by Katrina Owen](https://blog.splice.com/contributing-open-source-git-repositories-go/).
-
-### Testing
-
-fsnotify uses build tags to compile different code on Linux, BSD, OS X, and Windows.
-
-Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
-
-To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
-
-* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
-* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
-* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
-* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
-* When you're done, you will want to halt or destroy the Vagrant boxes.
-
-Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
-
-Right now there is no equivalent solution for Windows and OS X, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
-
-### Maintainers
-
-Help maintaining fsnotify is welcome. To be a maintainer:
-
-* Submit a pull request and sign the CLA as above.
-* You must be able to run the test suite on Mac, Windows, Linux and BSD.
-
-To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
-
-All code changes should be internal pull requests.
-
-Releases are tagged using [Semantic Versioning](http://semver.org/).

-# File system notifications for Go
-
-[![GoDoc](https://godoc.org/github.com/fsnotify/fsnotify?status.svg)](https://godoc.org/github.com/fsnotify/fsnotify) [![Go Report Card](https://goreportcard.com/badge/github.com/fsnotify/fsnotify)](https://goreportcard.com/report/github.com/fsnotify/fsnotify) [![Coverage](http://gocover.io/_badge/github.com/fsnotify/fsnotify)](http://gocover.io/github.com/fsnotify/fsnotify) 
-
-fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
-
-```console
-go get -u golang.org/x/sys/...
-```
-
-Cross platform: Windows, Linux, BSD and OS X.

-\* Android and iOS are untested.
-
-Please see [the documentation](https://godoc.org/github.com/fsnotify/fsnotify) for usage. Consult the [Wiki](https://github.com/fsnotify/fsnotify/wiki) for the FAQ and further information.
-
-## API stability
-
-fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA). 
-
-All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
-
-Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.

 ## Supporting Go flags when using pflag

+
+klog is a permanent fork of https://github.com/golang/glog.
+
+## Why was klog created?
+
+The decision to create klog was one that wasn't made lightly, but it was necessary due to some
+drawbacks that are present in [glog](https://github.com/golang/glog). Ultimately, the fork was created due to glog not being under active development; this can be seen in the glog README:
+
+> The code in this repo [...] is not itself under development
+
+This makes us unable to solve many use cases without a fork. The factors that contributed to needing feature development are listed below:
+
+ * `glog` [presents a lot "gotchas"](https://github.com/kubernetes/kubernetes/issues/61006) and introduces challenges in containerized environments, all of which aren't well documented.
+ * `glog` doesn't provide an easy way to test logs, which detracts from the stability of software using it
+ * A long term goal is to implement a logging interface that allows us to add context, change output format, etc.
+ 
+Historical context is available here:
+
+ * https://github.com/kubernetes/kubernetes/issues/61006
+ * https://github.com/kubernetes/kubernetes/issues/70264
+ * https://groups.google.com/forum/#!msg/kubernetes-sig-architecture/wCWiWf3Juzs/hXRVBH90CgAJ
+ * https://groups.google.com/forum/#!msg/kubernetes-dev/7vnijOMhLS0/1oRiNtigBgAJ

+
+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`.

+
+Leveled execution logs for Go.
+
+This is an efficient pure Go implementation of leveled logs in the
+manner of the open source C++ package
+	https://github.com/google/glog
+
+By binding methods to booleans it is possible to use the log package
+without paying the expense of evaluating the arguments to the log.
+Through the -vmodule flag, the package also provides fine-grained
+control over logging at the file level.
+
+The comment from glog.go introduces the ideas:
+
+	Package glog implements logging analogous to the Google-internal
+	C++ INFO/ERROR/V setup.  It provides functions Info, Warning,
+	Error, Fatal, plus formatting variants such as Infof. It
+	also provides V-style logging controlled by the -v and
+	-vmodule=file=2 flags.
+
+	Basic examples:

+		glog.Info("Prepare to repel boarders")
+
+		glog.Fatalf("Initialization failed: %s", err)
+
+	See the documentation for the V function for an explanation
+	of these examples:
+
+		if glog.V(2) {
+			glog.Info("Starting transaction...")
+		}
+
+		glog.V(2).Infoln("Processed", nItems, "elements")

+
+The repository contains an open source version of the log package
+used inside Google. The master copy of the source lives inside
+Google, not here. The code in this repo is for export only and is not itself
+under development. Feature requests will be ignored.
