+== master (unreleased)
+
+Upgrade considerations::
+  * Node.js packaging changes!
+    With the arrival of Asciidoctor.js 2.0.0 you can now use a command line interface (CLI) just like with Asciidoctor Ruby:
+
+    $(npm bin)/asciidoctor -r @asciidoctor/reveal.js -b revealjs presentation.adoc
++
+If you want to keep generating your reveal.js presentations using the Node.js API, you need to change the following code.
+Instead of:
+
+    var asciidoctorRevealjs = require('asciidoctor-reveal.js');
+    asciidoctorRevealjs.register()
++
+Use:
+
+    var asciidoctor = require('@asciidoctor/core')()
+    var asciidoctorRevealjs = require('@asciidoctor/reveal.js')
+    asciidoctorRevealjs.register()
++
