Intended audience. This document is intended for those who want to create their own themes to change the look and feel provided by Liferay. It is expected that readers have knowledge of Velocity or JSPs and XML. Knowledge of Java packaging is also useful when time comes to deploy the theme. Themes can be developed in the extension environment or as an independent artifact deployed as a WAR file.

Liferay version. This guide has been written for Liferay 4. It includes information for upgrading from 4.1 and some previous versions.

More information and support. If you are looking for help for a specific issue we invite you to use our community forums: http://www.liferay.com/web/guest/devzone/forums to ask your questions. We also offer professional support services (support@liferay.com) where your company will be assigned a Liferay developer ensuring your questions are answered promptly so that your project is never compromised. Purchased support always gets first priority. This business model allows us to build a company that can contribute a great portal to the open source community. If your company uses Liferay, please consider purchasing support. Liferay has an extremely liberal license model (MIT, very similar to Apache and BSD), which means you can rebundle Liferay, rename it, and sell it under your name. We believe free means you can do whatever you want with it. Our only source of revenue is from professional support and consulting.
