 2. Remove all Sprockets directives such as `//= require jquery` from `application.js` and elsewhere.  Instead establish JavaScript dependencies using AMD-style `define()` and `require()` calls.
 
-3. Use `requirejs_include_tag` at the top-level of your app's layout(s).  `javascript_include_tag` should be used to reference your top-level JavaScript modules.  Other modules will be pulled in dynamically by `require.js` in development and by `r.js` for optimized production builds.

 ## Changes
 
 Usage changes that impact folks upgrading along the 0.x series are documented here.
+
+### v0.5.1
+
+- `requirejs_include_tag` now generates a data-main attribute if given an argument, ala:
+
+    ```erb
+	<%= requirejs_include_tag "application" %>
+	```
+
+    This usage is preferred to using a separate `javascript_include_tag`, which will produce errors from require.js or r.js if the included script uses define anonymously, or not at all.
 
 ### v0.5.0
 
 - `application.js` is configured as the default top-level module for r.js builds.
 - It is no longer necessary or desirable to specify `baseUrl` explicitly in the configuration.
