-    \begin{itemize}
-      \item \typew{cd \$SSAX}
-      \item \typew{patch -p1 < \$sunet/httpd/surflets/SSAX-goodhtml-patch}

+  \item Uncompress and untar both tarballs in the same directory.
+  This will create a directory called \name{SSAX}, to which I will
+  refer to as \typew{\$SSAX}.  The package kit will add a file
+  \name{pkg-def.scm} to the \name{SSAX} directory.
+
+  \item Install SSAX as a scsh package by issuing the command
+  \typew{scsh-install-pkg --prefix /path/to/your/package/root} in the

+  utility of Michel Schinz, you can obtain it from

+
+  If you don't want to install SSAX with the packaging utility, you
+  can adjust the scripts to directly load the SSAX package definitions
