+## About
+This library makes heavy use of `Elm`, the delightful functional programming langauge.
+All of the HTML rendering, ANSI escape code parsing, user input handling happens in Elm.
+Check out [term package](https://github.com/wsowens/term.git) for more details on how this was implemented.
+
+Unfortunately, Elm packages cannot interact with WebSockets without the use of Ports and a bit of boilerplate JavaScript.
+This repo includes a simple Elm application based on the `term` package, with all the proper ports and boilerplate code.
+This all compiles down to a simple JavaScript file. (About 16KB once minified and gzipped!)
