Congratulations! You have a Joomla site! Joomla makes it easy to build a website just the way you want it and keep it simple to update and maintain. Joomla is a flexible and powerful platform.
Joomla is open source, which means you can make it work just the way you want it to. Start off using your site by logging in using the administrator account you created when you installed Joomla.
The basic Joomla installation will let you get a great site up and running, but when you are ready for more features the power of Joomla is in the creative ways that developers have extended it to do all kinds of things.
