+.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

 A Comic Book Archive is just an archive with a bunch of sequentially-named
 images in it which collate ASCIIbetically to the order in which they should be
 read. Each image corresponds to a page presented by a comic book reader and a
 Comic Book Archive represents a digital comic book.
 
-No guarantees can be made regarding image format, image names (though you can
-expect them to match [:digit:]*\..*; that is, a bunch of numbers followed by a
-file extension), archive attributes (compression or metadata), or what is in
-archives besides the images. In fact, when a comic book only has one image, the
-most common type of file in a comic book archive may not be an image at all.
+No guarantees can be made regarding image format, image names, archive
+attributes (compression or metadata), or what is in archives besides the
+images. In fact, when a comic book only has one image, the most common type of
+file in a comic book archive may not be an image at all.
 
 The extension corresponds to what type of archive is being used. I haven't seen
 an extension that hasn't fit within DOS 8.3, which makes sense as amateur
 skiddies and repackers mostly use Windows.

 .SH SYNOPSIS
 
-lowercase (-f)
+lowercase
 
 .SH DESCRIPTION
 
-Lowercase prints text from standard input to standard output as lowercase.
-
-.SH DIAGNOSTICS
-
-Lowercase will print an error message and exit with the appropriate status from sysexits(3) if it attempts
-to process a glyph outside the supported encoding range; this is to not inadverdently mangle multi-byte
-characters. The -f option exists to override this and process every character anyway.
+Lowercase prints text from standard input to standard output as lowercase. It
+passes through text it can't convert.
 
 .SH BUGS
 
-Lowercase is not Unicode aware unless it's compiled with the USE_ICU flag, which requires libicu.
-This isn't tested to any extent.
+Lowercase is not Unicode aware.
 .PP
-Lowercase is redundant to usages of tr(1) among other POSIX-specified utilities.
+Lowercase is redundant to usages of tr(1) among other POSIX-specified
+utilities.
