+docopt-go
+=========
+
+[![Build Status](https://travis-ci.org/docopt/docopt.go.svg?branch=master)](https://travis-ci.org/docopt/docopt.go)
+[![Coverage Status](https://coveralls.io/repos/docopt/docopt.go/badge.png)](https://coveralls.io/r/docopt/docopt.go)
+[![GoDoc](https://godoc.org/github.com/docopt/docopt.go?status.png)](https://godoc.org/github.com/docopt/docopt.go)
+
+An implementation of [docopt](http://docopt.org/) in the
+[Go](http://golang.org/) programming language.
+
+**docopt** helps you create *beautiful* command-line interfaces easily:
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/docopt/docopt-go"
+)
+
+func main() {
+	  usage := `Naval Fate.
+
+Usage:
+  naval_fate ship new <name>...
+  naval_fate ship <name> move <x> <y> [--speed=<kn>]
+  naval_fate ship shoot <x> <y>
+  naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
+  naval_fate -h | --help
+  naval_fate --version
+
+Options:
+  -h --help     Show this screen.
+  --version     Show version.
+  --speed=<kn>  Speed in knots [default: 10].
+  --moored      Moored (anchored) mine.
+  --drifting    Drifting mine.`
+
+	  arguments, _ := docopt.Parse(usage, nil, true, "Naval Fate 2.0", false)
+	  fmt.Println(arguments)
+}
+```
+
+**docopt** parses command-line arguments based on a help message. Don't
+write parser code: a good help message already has all the necessary
+information in it.
+
+## Installation
+
+⚠ Use the alias “docopt-go”. To use docopt in your Go code:
+
+```go
+import "github.com/docopt/docopt-go"
+```
+
+To install docopt according to your `$GOPATH`:
+
+```console
+$ go get github.com/docopt/docopt-go
+```
+
+## API
+
+```go
+func Parse(doc string, argv []string, help bool, version string,
+    optionsFirst bool, exit ...bool) (map[string]interface{}, error)
+```
+Parse `argv` based on the command-line interface described in `doc`.
+
+Given a conventional command-line help message, docopt creates a parser and
+processes the arguments. See
+https://github.com/docopt/docopt#help-message-format for a description of the
+help message format. If `argv` is `nil`, `os.Args[1:]` is used.
+
+docopt returns a map of option names to the values parsed from `argv`, and an
+error or `nil`.
+
+More documentation for docopt is available at
+[GoDoc.org](https://godoc.org/github.com/docopt/docopt.go).
+
+## Testing
+
+All tests from the Python version are implemented and passing
+at [Travis CI](https://travis-ci.org/docopt/docopt.go). New
+language-agnostic tests have been added
+to [test_golang.docopt](test_golang.docopt).
+
+To run tests for docopt-go, use `go test`.
