+# UUID package for Go language
+
+This is a fork of satori/go.uuid that won't change the existing API.
+
+[![Build Status](https://travis-ci.org/kevinburke/go.uuid.png?branch=master)](https://travis-ci.org/kevinburke/go.uuid)
+[![Coverage Status](https://coveralls.io/repos/github/kevinburke/go.uuid/badge.svg?branch=master)](https://coveralls.io/github/kevinburke/go.uuid)
+[![GoDoc](http://godoc.org/github.com/kevinburke/go.uuid?status.png)](http://godoc.org/github.com/kevinburke/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/kevinburke/go.uuid
+
+## Requirements
+
+UUID package requires Go >= 1.5.
+
+## Example
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/kevinburke/go.uuid"
+)
+
+func main() {
+ // Creating UUID Version 4
+ u1 := uuid.NewV4()
+ fmt.Printf("UUIDv4: %s\n", u1)
+
+ // Parsing UUID from string input
+ u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
+ if err != nil {
+ fmt.Printf("Something gone wrong: %s", err)
+ }
+ fmt.Printf("Successfully parsed: %s", u2)
+}
+```
+
+## Documentation
+
