-# Pure Go UUID implementation
-
-This package provides immutable UUID structs and the functions
-NewV3, NewV4, NewV5 and Parse() for generating versions 3, 4
-and 5 UUIDs as specified in [RFC 4122](http://www.ietf.org/rfc/rfc4122.txt).
-
-## Installation
-
-Use the `go` tool:
-
- $ go get github.com/nu7hatch/gouuid
-
-## Usage
-
-See [documentation and examples](http://godoc.org/github.com/nu7hatch/gouuid)
-for more information.
