We're happy to kick off our new series, Introduction to Omega 3.x. The Omega theme is the second most installed Drupal theme, and is used by over 40,000 sites. It is a very popular responsive base theme, with a lot of configuration options to help you get up and running. In the series we will be covering all of the pieces of your first Omega sub-theme, from an explanation of how a base theme works, all the way to making your own customizations to theme templates and functions from the Omega base.
The first two videos in the series are free, so you can get a sense of what will be covered and get an overview of Omega, helper modules often used with it, the terminology it uses, and finding documentation.
