+     "NJSON aims to make it convenient for one to decode, encode,
+and process JSON data, in the minimum keystrokes/minutes possible.
+
+NJSON is parser-independent, with existing Common Lisp JSON parsers being
+loadable as additional system.  @code{cl-json} is included by default, though.
+Conveniences that NJSON provides are:
+
+@itemize
+
+@item @code{encode} and @code{decode} as single entry points for JSON reading
+and writing, be it from streams/string/files, or from those.
+
+@item @code{jget}, @code{jrem}, @code{jtruep}, and their aliases to
+access/delete the decoded objects' properties and check their truth value
+without the need to worry about the low-level details of how these values are
+decoded.
+
+@item @code{jif}, @code{jwhen}, @code{jor}, @code{jand}, and other macros
+mimicking Lisp ones, while using truth values of JSON-decoded data.
+
+@end itemize\n")
