+       "Org Ref is an Emacs library that provides rich support for citations,
+labels and cross-references in Org mode.
 
-The default setup uses helm-bibtex.
+The basic idea of Org Ref is that it defines a convenient interface to insert
+citations from a reference database (e.g., from BibTeX files), and a set of
+functional Org links for citations, cross-references and labels that export
+properly to LaTeX, and that provide clickable functionality to the user.  Org
+Ref interfaces with Helm BibTeX to facilitate citation entry, and it can also
+use RefTeX.
 
-You should really read org-ref.org in this package for details.")
+It also provides a fairly large number of utilities for finding bad citations,
+extracting BibTeX entries from citations in an Org file, and functions to
+create and modify BibTeX entries from a variety of sources, most notably from
+a DOI.
+
+Org Ref is especially suitable for Org documents destined for LaTeX export and
+scientific publication.  Org Ref is also useful for research documents and
+notes.")
