+# UUID package for Go language
+
+[![Build Status](https://travis-ci.org/satori/go.uuid.svg?branch=master)](https://travis-ci.org/satori/go.uuid)
+[![Coverage Status](https://coveralls.io/repos/github/satori/go.uuid/badge.svg?branch=master)](https://coveralls.io/github/satori/go.uuid)
+[![GoDoc](http://godoc.org/github.com/satori/go.uuid?status.svg)](http://godoc.org/github.com/satori/go.uuid)
+
+This package provides pure Go implementation of Universally Unique Identifier (UUID). Supported both creation and parsing of UUIDs.
+
+With 100% test coverage and benchmarks out of box.
+
+Supported versions:
+* Version 1, based on timestamp and MAC address (RFC 4122)
+* Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1)
+* Version 3, based on MD5 hashing (RFC 4122)
+* Version 4, based on random numbers (RFC 4122)
+* Version 5, based on SHA-1 hashing (RFC 4122)
+
+## Installation
+
+Use the `go` command:
+
+	$ go get github.com/satori/go.uuid
+
+## Requirements
+
+UUID package requires Go >= 1.2.
+
+## Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/satori/go.uuid"
+)
+
+func main() {
+	// Creating UUID Version 4
+	// panic on error
+	u1 := uuid.Must(uuid.NewV4())
+	fmt.Printf("UUIDv4: %s\n", u1)
+
+	// or error handling
+	u2, err := uuid.NewV4()
+	if err != nil {
+		fmt.Printf("Something went wrong: %s", err)
+		return
+	}
+	fmt.Printf("UUIDv4: %s\n", u2)
+
+	// Parsing UUID from string input
+	u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
+	if err != nil {
+		fmt.Printf("Something went wrong: %s", err)
+	}
+	fmt.Printf("Successfully parsed: %s", u2)
+}
+```
