 2. Download the precompiled zip archive corresponding with the [Elixir Release](https://github.com/elixir-lang/elixir/releases/) you wish to build the installer for.
-3. Extract the contents of the zip archive into a folder called `elixir` in the repo directory.
-4. Open either a Command Prompt or PowerShell in the repo directory.
-5. In the directory, run `#PathToInnoSetup#\ISCC.exe /dElixirVersion=#Version# Elixir.iss` where `#PathToInnoSetup#` is probably "C:\Program Files (x86)\Inno Setup 5" and where `#Version#` matches the version of the precompiled package (ex. 0.14.1).
