+# 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.
