+# elixir-windows-setup
 
-This installer, part of the Elixir on Windows Google Summer of Code 2014 project, is a work in progress.  Jordan Russell's [Inno Setup](http://www.jrsoftware.org/isinfo.php) makes it possible, and if you download a copy of the compiler, you can try the installer out.
+Part of the Elixir on Windows Google Summer of Code 2014 project, this installer sets up [Elixir](http://elixir-lang.org/) on a Windows machine.
+
+Currently, it will:
+* Download the precompiled Elixir package
+* Extract the package to your favorite directory (or mine)
+* Create shortcuts to IEx and the uninstaller
+
+Currently, it won't:
+* Download the LATEST version of Elixir (currently hardcoded to v0.14.1)
+* (Suggest that the user) install Erlang first
+* Append the user's Path variable
