Getting started is pretty simple. Head to CrunchBang's main site, find the Download section, and grab the main ISO file (from BitTorrent or directly). You can burn it to CD/DVD, load it as a virtual system in VirtualBox/VMWare, or install it on a flash drive with UNetbootin. Put your CD or USB drive into your system, or boot your virtualization tool, and hit Enter at the boot prompt to load the live session of CrunchBang.
