+Dict provides the following functions for querying dictionary servers

+- Function: dict-match-word word :: Return a list of dictionary matches

+- Function: dict-define-word word :: Return the dictionary definition of

+The function ~dict-match-word~ queries the dictionary server for words
+that match a given input in the dictionary specified by the user option
+~dict-dictionary~, based on the matching strategy specified by the
+~dict-strategy~.  Similarly, ~dict-define-word~ retrieves and returns

+~dict-dictionary~ as a string, or it returns ~nil~ if the dictionary
+server doesn't find a definition for that word.

-** dictionary
+The main motivation behind the development of Dict was to resolve some
+issues that the author came across with the =dictionary.el= package that
+ships with Emacs.  This package, initially written by Torsten Hilbrich
+to support both GNU Emacs and XEmacs, was added as a library to Emacs
+core in version 28.
 
-** define-word
+In their essence, Dict and =dictionary.el= have similar goals and they
+both operate in a similar manner - getting word definitions from RFC2229
+servers, and displaying them in an Emacs buffer.
 
-** DictEm
+Dict's differentiation comes from its simplicity and
+extensibility--while =dictionary.el= defines a bespoke major mode and
+interface for browsing word definitions, Dict leverages Emacs's Help
+mode by default, and let's you extend and control every aspect of its
+behavior via customization options.
 
+=dict.el= is also shorter than =dictionary.el=--just under 300 lines of code!
