+ABOUT
+
+    Termighty is a script package designed for use with the TinTin++ MUD client and the
+    Aardwolf MUD (http://aardwolf.com). It is meant to provide quality of life features
+    for players on UNIX-like platforms with minimal resource consumption or distraction.
+
+    An explicit goal of Termighty is to keep compatibility with modern versions of
+    TinTin++ and tmux, as well as to be easy to update and maintain for anyone who
+    wishes to do so.
+
+    Termighty is named in honor of the mighty terminal, from which one can have a
+    first-class MUDding experience; and the humble termite, a favorite snack of the
+    aardwolf.
+
+INFO
+
+    Players can download the package, run bin/termighty, and play.
+
+    Anyone interested in development of Termighty should peruse the HTML documentation
+    in docs/
+
+    Termighty attempts to keep up to date with TinTin++ and tmux. Presently it is
+    developed and tested against:
+
+        - TinTin++ 2.02.03 (2020-05-15) - https://tintin.mudhalla.net/
+        - tmux 3.1b (2020-05-04) - https://github.com/tmux/tmux
