+## istanbul-lib-instrument
+
+[![Build Status](https://travis-ci.org/istanbuljs/istanbul-lib-instrument.svg?branch=master)](https://travis-ci.org/istanbuljs/istanbul-lib-instrument)
+
+Istanbul instrumenter library.
+
+Version 1.1.x now implements instrumentation using `Babel`. The implementation is inspired
+by prior art by @dtinth as demonstrated in the `__coverage__` babel plugin.
+
+It provides 2 "modes" of instrumentation.
+
+-   The old API that is mostly unchanged (except for incompatibilities noted) and
+    performs the instrumentation using babel as a library.
+
+-   A `programVisitor` function for the Babel AST that can be used by a Babel plugin
+    to emit instrumentation for ES6 code directly without any source map
+    processing. This is the preferred path for babel users. The Babel plugin is
+    called `babel-plugin-istanbul`.
+
+Incompatibilities and changes to instrumentation behavior can be found in
+[v0-changes.md](v0-changes.md).
