Another good Scheme implementation is [Chicken](http://www.call-cc.org). For our purposes, this is in some respects
superior to Racket, and in other respects inferior. If you have any issues with installing or using Racket, you could
try this out instead. You might even want to install both.

This last installation is less crucial than the others, since we will be focusing
* As mentioned, **GHC** is the main Haskell engine or compiler you'll be installing. The current version is 7.8.4, from December 2014.
* **gcc** and **llvm/clang** and **Xcode** and **MinGW** are names for other compilers on various systems. Oftentimes these will be used during the installation process to get GHC up and running. Some of the strategies described below will help you install these if they're not already on your machine.
* **alex** and **happy** and **haddock** are names of various Haskell helper programs that GHC uses to get up and running.
-* **[Cabal](https://www.haskell.org/cabal)** is a "package manager" for Haskell. It allows you to install libraries or extensions that other people have built. (Usually those are published at the [Hackage](https://hackage.haskell.org) web site.) Some of these are experimental and may not always work; others are quite fundamental and are almost de facto parts of what people expect in a Haskell system.
-* **[Haskell Platform](https://www.haskell.org/platform)** is a standard bundle that includes a specific version of GHC, plus specific versions of some of the most popular libraries or extensions. This is updated once or twice a year. The current version is 2014.2.0.0, from August 2014. It includes GHC version 7.8.3.

The easiest way to get up and running with Haskell/GHC is to install the Haskell Platform. Here's how to do that **on Windows**:
* In a Terminal, type `sudo apt-get install haskell-platform`.
-It's useful to know about the general [Haskell wiki](https://wiki.haskell.org) (not restricted to just GHC). They have a [Getting Started](https://wiki.haskell.org/Haskell_in_5_steps) page, which also recommends that you install the Haskell Platform.

If any of the instructions above don't work, then you can try alternative instructions for [Mac](http://new-www.haskell.org/downloads/osx) or [Windows](http://new-www.haskell.org/downloads/windows) or [Ubuntu](http://new-www.haskell.org/downloads/linux). Note that this method doesn't install all the extensions that are part of the Haskell Platform, but only the core pieces of GHC. You can use Cabal to download and manage any extra extensions you turn out to need, down the road.
**After installing Haskell**, open a Terminal and type:
