+.TH TRINITX 7
+
+.SH PRONUNCIATION
+"Try LSD"
+
+.SH SYNOPSIS
+.I TriLSD
+is a UNIX-like software distribution built upon the Linux kernel and the
+musl C standard library, with nearly all configuration options left to the
+user's own device.
+
+.SH BASE SYSTEM
+A
+.I TriLSD
+system always has the following packages:
+dash,
+the GNU compiler collection,
+GNU make,
+musl,
+and
+linux and util-linux.
+.PP
+In addition,
+.I TriLSD
+needs a core utilities package.
+The GNU coreutils are a popular choice but Busybox or your own may be used.
+.PP
+.I TriLSD
+also needs an initialization system.
+OpenRC is the suggested choice but others may be used.
+SystemD is discouraged; it's mentioned for its popularity and frowned upon for
+its generally lax security.
+
+.SH INSTALLATION
+To install
+.I TriLSD
+most of the POSIX specified utilities including awk, git(1), GNU make, and a C
+compiler that can build the GNU compiler collection must be installed.
+
+.PP
+For the installation process see
+.RB try (1)
+
+.SH PACKAGE MANAGEMENT
+.I TriLSD
+does not come with a package manager; the user may choose whatever
+system-independent package manager they prefer.
+
+.SH CONTRIBUTING
+Pay attention to projects' guidelines for distributions.
+.PP
+musl guidelines: https://wiki.musl-libc.org/guidelines-for-distributions.html
+
+.SH HISTORY
+The
+.I TriLSD
+project was started 2021-12-28 as Trinitx.
+
+.SH COPYRIGHT
+.I TriLSD
+documentation and all in-house tools are part of the public domain.
+Components of the distribution are of course subject to their own licenses.
+
+.SH SEE ALSO
