What am I Downloading?
concrete5 is middleware. It was designed for a LAMP stack but works on Windows webservers running IIS and PHP as well.
It is NOT a desktop application you run on your local computer to design a website. If you're comfortable configuring webservers and you want a great free CMS to tinker with, download away. If most of this sounded like greek to you, try a insta-setup on our servers instead and you'll get a copy running in seconds, which you can turn into a hosting account we can actually support as well.
Latest Stable Version
NOTE: Many add-ons haven't been updated to work with 5.5 yet. If you've got an existing site that relies on stuff in the marketplace, you should try running this update on a backup copy of your site before upgrading live.
