 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 it to be installed 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 install Grammar Parser 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. Most Drupal modules that expect Grammar Parser to be
+installed as a library 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.

+if you are installing Grammar Parser as a module under a version of Drupal other
+than 7.x, you will need to edit the grammar_parser.info file to change the
+core/version lines to the correct Drupal version in order to enable it.
