"When you first install Slackware, you'll be given the option of
installing all packages that are in the official Slackware
repository. This is recommended practice, since it will eliminate
any dependency problems you may encounter if you were to just pick
and choose packages. (Besides, there's not a whole lot in the
official repository, so it won't take up much disk space.)
"Before you can update your system, you'll need to edit the
"/etc/slackpkg/mirrors" file, in order to choose a download mirror.
Find the appropriate section for your version of Slackware, and
un-comment the appropriate line for the mirror that you wish to
use. (Note that you can only choose one mirror at a time. Also note
that some mirrors work better than others, so you may have to try a
couple to get satisfactory results.)"
