README.md directs users to import using gopkg.in

(for both V1 and V2)

This method now works with version agnostic and version aware Go build
tools.

+## Use with Import Statement
+
+[The proposal to add package version support to the Go
+toolchain](https://github.com/golang/go/issues/24301) requires library
+authors to leave V1 code in the top level directory of the repository,
+and create a `v2` directory for V2 of the library.
+
+However this library was tagged with a `v2` release prior to that
+proposal, and V1 of this library is no longer at the top level of the
+repository. For a while this conflict prevented `go build` and `vgo
+build` from both being able to build a program that requires this
+library.
+
+Because of a [update to
+`vgo`](https://github.com/golang/go/issues/24099) that provides
+enhanced support for gopkg.in, now building projects that use either
+version agnostic *or* version aware Go build tools will work, provided
+this library is imported using its gopkg.in path.

+### To use V2 of this library:
