-## Experimental HCL2
-
-This repository contains the experimental version 2 of HCL. This new version
-combines the initial iteration of HCL with the interpolation language HIL
-to produce a single configuration language that supports arbitrary expressions.
-
-At this time the HCL2 syntax and the Go API are still evolving.
-Backward-compatibility is not guaranteed and so any application using this
-library should use vendoring.

-The new implementation has a completely new parser and Go API, with no direct
-migration path. Although the syntax is similar, the implementation takes some
-very different approaches to improve on some "rough edges" that existed with
-the original implementation and to allow for more robust error handling.
-
-Once this new implementation reaches stability, its package paths will be
-changed to reflect that it is the _current_ HCL implementation. At that time,
-the original implementation will be archived.

 ## Why?
 
 Newcomers to HCL often ask: why not JSON, YAML, etc?

+Version 2.0 of HCL combines the features of HCL 1.0 with those of the
+interpolation language HIL to produce a single configuration language that

+It's possible to import both HCL 1 and HCL 2 into the same program using Go's
+_semantic import versioning_ mechanism:
+
+```go
+import (
+ hcl1 "github.com/hashicorp/hcl"
+ hcl2 "github.com/hashicorp/hcl/v2"
