+A standalone implementation of hash table in JavaScript. It associates keys with values, and allows any object to be used as the key (unlike JavaScript's built-in `Object`, which only allows strings as property names).
+Also included is a hash set implementation, implemented by wrapping the keys of a hash table.
+
+jshashtable requires no libraries and is designed to work in all ECMAScript 3 compliant environments, including all major browsers and Node.js. In particular, it has been tested and works in:
+
+- Firefox (all versions, back to Phoenix 0.1)
+- Internet Explorer 5.5+
+- Safari 3+ (untested in previous versions)
+- Google Chrome (all versions)
+- Opera 7+
+
+See the [jshashtable website](http://timdown.co.uk/jshashtable/) for full documentation.
