Now that I was finally able to load the site I must say I'd have liked to have had some basic tutorials to help me get started. It might haven't been in the scope of this site but surely it would have been nice. Also the recaptcha is just a kick in the balls when it starts asking to pick the right squares. I'd have been happy to sign in with G+ just to skip it.
Hi, thanks for the feedback. We're planning to add some basic tutorials soon like (http://training.play-with-docker.com). We'd need the help from the community though as it's hard for us to grow an OS project by ourselves. Regarding the login thing, we're also working on that aspect. Expect some updates soon.
