+# uuid 
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services.
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid). It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice. One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
+
+###### Install
+`go get github.com/google/uuid`
+
+###### Documentation
+[](http://godoc.org/github.com/google/uuid)
+
+Full `go doc` style documentation for the package can be viewed online without
+installing this package by using the GoDoc site here:
+http://godoc.org/github.com/google/uuid
