+# Game of Life - Java version
+
 Original source downloaded [from Vintage Basic](http://www.vintage-basic.net/games.html)
 
 Conversion to [Oracle Java](https://openjdk.java.net/)
+
+## Requirements
+
+* Requires Java 17 (or later)
+
+## Notes
+
+The Java version of Game of Life tries to mimics the behaviour of the BASIC version.
+However, the Java code does not have much in common with the original.
+
+**Differences in behaviour:**
+* Input supports the ```.``` character, but it's optional.
+* Evaluation of ```DONE``` input string is case insensitive.
