+# Conway's Life
+
+Original from David Ahl's _Basic Computer Games_, downloaded from http://www.vintage-basic.net/games.html.
+
+Ported to Rust by Jon Fetter-Degges
+
+Developed and tested on Rust 1.64.0
+
+## How to Run
+
+Install Rust using the instructions at [rust-lang.org](https://www.rust-lang.org/tools/install).
+
+At a command or shell prompt in the `rust` subdirectory, enter `cargo run`.
+
+## Differences from Original Behavior
+
+* The simulation stops if all cells die.
+* Input of more than 66 columns is rejected. Input will automatically terminate after 20 rows. Beyond these bounds, the original
+implementation would have marked the board as invalid, and beyond 68 cols/24 rows it would have had an out of bounds array access.
+* The check for the string "DONE" at the end of input is case-independent.
