Wherever on this site you see a box like this with text in a monospaced font, it means you will have to open a terminal window and type the text after the dollar sign ($) in your terminal:

$ echo "Hello world"

Some software you are likely to need:

Ruby on Rails

A great web development framework. Installation instructions are here: www.rubyonrails.com/down.

RubyGems (gem)

The standard package manager for Ruby. Download RubyGems here, then extract the archive and run 'ruby setup.rb'. Once it is installed, it can be used like this:

Install package 'mongrel':

$ gem install mongrel

List all installed packages:

$ gem list

List all available packages with names containing 'mongrel'

$ gem list --remote | grep mongrel

wget

Wget is a command line utility used to download files available on the web. You could also download files with your browser, but if you are typing on your web server in terminal window, wget is the way to go. Install like this on Debian: 'apt-get install wget'.

Subversion (svn)

A version control system. The command 'svn' is often used to get the most recent version of a software package. Install like this on Debian: 'apt-get install svn'. If you're on Mac OS X, check out my Subversion tutorial: www.rubyrobot.org/tutorial/subversion-with-mac-os-x
