 In the context of Drupal, this project is available as:
 - a library using the Libraries API (2.x-dev), and
 - a Drupal module (the Drupal project API does not offer a library type).
+If you are using a Drupal module that depends on using Grammar Parser, you will
+need to first figure out whether that module expects Grammar Parser to be used
+as a module or a library.
 
-If used as a library, then install it in a libraries directory (e.g.,
-"sites/all/libraries" or equivalent) but do not "enable" it as a module.
+If you need to use Grammar Parser as a library, then install it in a libraries

+do so via the Libraries API module (http://drupal.org/project/libraries), in
+which case you would also need to download, install, and enable the Grammar
+Parser Library module (http://drupal.org/project/grammar_parser_lib) so that the
+Libraries API module will recognize Grammar Parser as a library.

+core/version lines to the correct Drupal version in order to enable it.
