+**Be sure not to set an `id` attribute**. This is because the directive needs to maintain selector knowledge in order to handle buggy behavior in TinyMCE when DOM manipulation is involved, such as in a reordering of HTML through ng-repeat or DOM destruction/recreation through ng-if.
+
+## Working with ng-model
+
+The ui-tinymce directive plays nicely with the ng-model directive such as ng-required.
+
+If you add the ng-model directive to same the element as ui-tinymce then the text in the editor is automatically synchronized with the model value.
+
+_The ui-tinymce directive stores the configuration options as specified in the [TinyMCE documentation](http://www.tinymce.com/wiki.php/Configuration) and expects the model value to be a html string or raw text, depending on whether `raw` is `true` (default value is `false`)._
+
 ## Options
 
-All the TinyMCE options can be passed through the directive, as well as some helpers.
+The directive supports all of the standard TinyMCE initialization options as listed [here](http://www.tinymce.com/wiki.php/Configuration).
+
+In addition, it supports these additional optional options

+- `format` Format to get content as, i.e. 'raw' for raw HTML, or 'text' for text only. Documentation [here](http://www.tinymce.com/wiki.php/api4:method.tinymce.Editor.getContent)
+- `trusted` When `true`, all TinyMCE content that is set to `ngModel` will be whitelisted by `$sce`
