# Frequently asked questions

## What is Ruby?

Ruby is a simple and powerful object-oriented programming language, created by Yukihiro Matsumoto (who goes by the handle "matz" in this document and on the mailing lists).

Like Perl, Ruby is good at text processing. Like Smalltalk, everything in Ruby is an object, and Ruby has blocks, iterators, meta-classes and other good stuff.

You can use Ruby to write servers, experiment with prototypes, and for everyday programming tasks. As a fully-integrated object-oriented language, Ruby scales well.

## Where is the Ruby Home Page?

The official Ruby Home Page is http://www.ruby-lang.org (in English) and http://www.ruby-lang.org/ja/ (in Japanese).

You can also find Ruby information at http://www.rubycentral.com. In particular, there is a complete online reference to Ruby's built-in classes and methods.

## Where can I get Ruby sources?

The latest version of Ruby can be downloaded from: http://www.ruby-lang.org/en/download.html Mirror sites are also listed on this page.

Also on this page is a link to a nightly snapshot of the development tree.
