Thanks! In case you missed it elsewhere there's a tutorial by Wagtail contributor Serafeim Papastefanos here: https://gist.github.com/tomdyson/8974456 but we're working hard on official docs and a proper screencast.
Is that true in general for this CMS, that Python 2.7 will be needed? Python 3 isn't supported?
If anyone has time to test Wagtail on Python 3 and report any problems to https://github.com/torchbox/wagtail/issues that will accelerate the work!
