1. First, we need to make a folder for Joomla!. Open the folder that you installed
XAMPP into – usually C:\XAMPP or C:\Program Files\XAMPP on Windows.
2. Open up the folder “htdocs:”
3. Create a new folder in “htdocs” titled “joomla15.”
4. Now we need to download the latest copy of Joomla! 1.5 from the net. Go to http://
www.joomla.org and scroll down the left hand side to find “Download Latest” and
click on “1.5” to open the download page:

If you want to use Joomla as your main page and you are using Apache, you'd copy the joomla files to the /var/www directory. You'd then need to run the installation script from a browser.
