+# 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, macOS 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://splice.com/blog/contributing-open-source-git-repositories-go/).
+
+### Testing
+
+fsnotify uses build tags to compile different code on Linux, BSD, macOS, 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 macOS, 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)
+
+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 macOS.

+
+## 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`.
+
+## Usage
+
+```go
+package main
+
+import (
+	"log"
+
+	"github.com/fsnotify/fsnotify"
+)
+
+func main() {
+	watcher, err := fsnotify.NewWatcher()
+	if err != nil {
+		log.Fatal(err)
+	}
+	defer watcher.Close()
+
+	done := make(chan bool)
+	go func() {
+		for {
+			select {
+			case event, ok := <-watcher.Events:
+				if !ok {
+					return
+				}
+				log.Println("event:", event)
+				if event.Op&fsnotify.Write == fsnotify.Write {
+					log.Println("modified file:", event.Name)
+				}
+			case err, ok := <-watcher.Errors:
+				if !ok {
+					return
+				}
+				log.Println("error:", err)
+			}
+		}
+	}()
+
+	err = watcher.Add("/tmp/foo")
+	if err != nil {
+		log.Fatal(err)
+	}
+	<-done
+}
+```

+
+## FAQ
+
+**When a file is moved to another directory is it still being watched?**
+
+No (it shouldn't be, unless you are watching where it was moved to).
+
+**When I watch a directory, are all subdirectories watched as well?**
+
+No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
+
+**Do I have to watch the Error and Event channels in a separate goroutine?**
+
+As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
+
+**Why am I receiving multiple events for the same file on OS X?**
+
+Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
+
+**How many files can be watched at once?**
+
+There are OS-specific limits as to how many watches can be created:
+* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
+* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
+
+**Why don't notifications work with NFS filesystems or filesystem in userspace (FUSE)?**
+
+fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications.
