 ## HTMLFormRenderer
 
-Renders data returned by a serializer into an HTML form.  The output of this renderer does not include the enclosing `<form>` tags or an submit actions, as you'll probably need those to include the desired method and URL.  Also note that the `HTMLFormRenderer` does not yet support including field error messages.
+Renders data returned by a serializer into an HTML form. The output of this renderer does not include the enclosing `<form>` tags, a hidden CSRF input or any submit buttons.
 
-**Note**: The `HTMLFormRenderer` class is intended for internal use with the browsable API and admin interface. It should not be considered a fully documented or stable API. The template used by the `HTMLFormRenderer` class, and the context submitted to it **may be subject to change**.  If you need to use this renderer class it is advised that you either make a local copy of the class and templates, or follow the release note on REST framework upgrades closely.
+This renderer is not intended to be used directly, but can instead be used in templates by passing a serializer instance to the `render_form` template tag.
