 Features
 ----
-  - Current version supports Microsoft Office OpenXML DOCX format.
-  - Configurable brackets for tags-placeholders.
+  - Caching XSL template to filesystem for fast document render.
+  - Track document mode - generate and cache new template if original document was updated.
+  - Configurable brackets for placeholder tags.
   - Basic extension system, which helps generating content blocks such as Cells or ListItems.
-  - Caching XSL template to filesystem.
+
+Known issues
+----
+Values inserted into placeholder tags may be highlighted as incorrect by spellcheck, since library removes language attribute and MS Word tries to check it with system language.
