+greetd (A login manager daemon)
+
+greetd is a minimal and flexible login manager daemon that makes no
+assumptions about what you want to launch.
+
+Prior to installation you must create a user/group for 'greetd' on
+your system:
+
+'groupadd -g 381 greeter'
+'useradd -d /var/lib/greeter -u 381 -g greeter -G video -s /bin/false \
+greeter'
+
+To start 'greetd' at boot, ensure you've set runlevel 4 and copy the
+included '/etc/rc.d/rc.4.greetd' to '/etc/rc.d/rc.4.local' (or add the
+contents to your existing file) and reboot.
+
+The default greeter is 'agreety' which is included. This is a text-based
+greeter login that resembles a console login. You can change greetd to
+load any program upon boot by editing the '/etc/greetd/config.toml'
+file. In order to save any changes during an upgrade, it is recommended
+to copy the file to '/etc/greetd/greetd.conf' to save your personalized
+settings.
+
+*NOTE* You will see an error about "unable to set working directory",
+which appears to happen on all non-systemd distros, but doesn't
+effect overall use.
+
+There are many additional greeters for greetd, which have yet to be
+submitted to SBo, if you have a favorite, please upload a SlackBuild!

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
