The release ISO images should be available on most of the [[mirrors|mirrors]]. If the ISO is not available on a certain mirror, please try another one or download it from the DragonFly master site. Each image is in the "Live CD" format, meaning that it boots into a running and fully functional DragonFly system, which can be used for testing or system recovery tasks as well as installation. Check the [hardware page](http://www.dragonflybsd.org/docs/supportedhardware/) or boot a Live CD to check for compatibility.
The GUI bootable USB image also contains the DragonFly git repo in /usr/src and the pkgsrc git repo in /usr/pkgsrc. The code can be trivially checked out using these repos and can be incrementally updated from master sites, post-install.
