 pkgadd \- install software package
 .SH SYNOPSIS
-\fBpkgadd [options] <file>\fP
+\fBpkgadd [options] <package>\fP
 .SH DESCRIPTION
 \fBpkgadd\fP is a \fIpackage management\fP utility, which installs
 a software package. A \fIpackage\fP is an archive of files (.pkg.tar.gz).
 .SH OPTIONS
 .TP
 .B "\-u, \-\-upgrade"
-Upgrade/replace package with the same name as <file>.
+Upgrade/replace package with the same name as <package>. This action
+comprises several steps. First the contents of <package> are matched against
+the INSTALL NO directives in pkgadd.conf, and against those files listed in /var/lib/pkg/db
+that are NOT owned by the previously-installed version of <package>. Any file owned by the
+previously-installed version is considered eligible for overwriting, unless it matches an
+UPGRADE NO directive in pkgadd.conf.
+
+At this point pkgadd has constructed a "non-install" list, a "conflicting files" list, and a "keep"
+list. (The "keep" list is unique to an upgrade operation, but the other two lists also affect a
+regular install operation.)
+
+After writing the anticipated changes to the package database, \fIpkgadd\fP finishes by unpacking
+the contents of <package> onto the filesystem, using the "keep" list to shield wanted files from
+deletion, and the "conflicting files" list to skip the installation unless \-f is in effect. (See
+the next option.) Files that were not written to the disk are preserved under /var/lib/pkg/rejected
+(See the \fBCONFIGURATION\fP section for details).
