+# Rogue
+
+This is a portable version of the classic Unix game *Rogue*, forked from the
+version distributed with NetBSD. It's intended to be portable across Unix-like
+systems and maintains a user-specific high score table, in contrast to the
+systemwide, multiuser score list used by the traditional BSD *Rogue*.
+
+## Requirements and Installation
+
+The program requires some version of the curses library, such as ncurses. Run
+`make` to compile the program and `make install` to install it. The program is
+installed under `/usr/local` by default and thus must be installed as the
+`root` user, but the location can be customized by editing the makefile.
+
+This repository also includes a copy of "A Guide to the Dungeons of Doom," part
+of the classic *UNIX User's Supplementary Documents*, in `USD.doc`. This
+requires `groff` or another `troff`-compatible program, specified in the
+makefile. Run `make` from the `USD.doc` directory to generate `rogue.txt` and
+`less -R rogue.txt` to read the document.
+
+## History and Source
+
+The original *Rogue* was created around the year 1980 by Glenn Wichman, Michael
+Toy, and Ken Arnold. The version distributed in this repository is derived from
+a clone created by Timothy Stoehr. The source code was copied from the trunk
+branch of [the official NetBSD src Git mirror][1] in 2026. The file `HISTORY`
+contains a copy of the Git log for the project directory.
+
+## License
+
+The original source files contain both a three-clause BSD license and an
+informal license statement that forbids commercial use. (The USD document
+describes the program as "public domain," but this is obviously inaccurate.)
+New code added in this repository is licensed under an ISC-style license.
+See the `LICENSE` file for details.
