Obtaining DragonFly for your system
Images
DragonFly BSD images are 'live', meaning these images on whatever media will boot your system and let you log in as root (no password). You can use this feature to check for hardware compatibility and play with DragonFly a little before actually installing it on your hard drive. The CD includes an installer that can be run at the console. To activate the installer, boot and login as installer.
If you use a GUI DVD, you can login as root and start a GUI with startx. Note that there is no GUI release for the current release. You will need to install Xorg directly. If you use a USB .img file, it needs to be copied to a USB key directly. Use dd on unix-like systems, or a similar program on Windows. You could also try Image Writer for Windows.

Obtaining source via git
To clone the sources using git:
# cd /usr
# make src-create
This will fetch all sources for you from a fast mirror. If the git-clone command is not available update your Makefile to a recent version. If you do not have git installed, install it from dports (devel/git). See development(7) for further instructions how to work with the repository.
If you wish to check out the source repository manually, you can use
# git clone git://git.dragonflybsd.org/dragonfly.git dragonfly
All release CDs and images also have pkg installed for immediate download of packaged third-party software.
Browsing source via web interface
The DragonFly source can be browsed via the gitweb web interface.
DragonFly Releases
Releases occur approximately twice a year. DragonFly release branches only contain bug and security fixes and are designed for people running production systems who don't want any surprises. Brand-new features often discussed on the mailing lists are typically not in release branches.
DragonFly systems based on releases are labeled RELEASE, for example, you might be running DragonFly X.Y.Z-RELEASE. If you run a daily snapshot or track git master, you'll see X.Y.Z-DEVELOPMENT as your system version.
