+# Hello World
+
+The classical introductory exercise. Just say "Hello, World!".
+
+["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) is
+the traditional first program for beginning programming in a new language
+or environment.
+
+The objectives are simple:
+
+- Write a function that returns the string "Hello, World!".
+- Run the test suite and make sure that it succeeds.
+- Submit your solution and check it at the website.
+
+If everything goes well, you will be ready to fetch your first real exercise.
+
+## Setup
+
+Check out [Exercism Help](http://exercism.io/languages/common-lisp) for instructions to
+get started writing Common Lisp. That page will explain how to install and setup
+a Lisp implementation and how to run the tests.
+
+## Formatting
+
+While Common Lisp doesn't care about indentation and layout of code,
+nor whether you use spaces or tabs, this is an important consideration
+for submissions to exercism.io. Excercism.io's code widget cannot
+handle mixing of tab and space characters well so using only spaces is recommended to make
+the code more readable to the human reviewers. Please review your
+editors settings on how to accomplish this. Below are instructions for
+popular editors for Common Lisp.
+
+### VIM
+
+Use the following commands to ensure VIM uses only spaces for
+indentation:
+
+```vimscript
+:set tabstop=2
+:set shiftwidth=2
+:set expandtab
+```
+
+(or as a oneliner `:set tabstop=2 shiftwidth=2 expandtab`). This can
+be added to your `~/.vimrc` file to use it all the time.
+
+### Emacs
+
+Emacs is very well suited for editing Common Lisp and has many
+powerful add-on packages available. The only thing that one needs to
+do with a stock emacs to make it work well with exercism.io is to
+evaluate the following code:
+
+`(setq indent-tab-mode nil)`
+
+This can be placed in your `~/.emacs` (or `~/.emacs.d/init.el`) in
+order to have it set whenever Emacs is launched.
+
+One suggested add-on for Emacs and Common Lisp is
+[SLIME](https://github.com/slime/slime) which offers tight integration
+with the REPL; making iterative coding and testing very easy.

+
+This is an exercise to introduce users to using Exercism [http://en.wikipedia.org/wiki/%22Hello,_world!%22_program](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program)
+
+## Submitting Incomplete Solutions
+It's possible to submit an incomplete solution so you can see how others have completed the exercise.
