By popular request, the Windows nightlies now include an installer version as well. Now you no longer have to deal with boring old manually copying files, and get to beta-test an extra piece of software as well! I realize this might make some documentation obsolete, but not like you were reading it anyways.
Also my legal council would like me to remind you to not install a nightly on top of 1.0. The consequences to the universe might be catastrophic. Just uninstall 1.0 if you’re going that route, you’re likely not going back to it.
