The doc has been updated, but there was a problem while pushing it this morning. We are working on it.

Documentation is definitely part of the process :) Apparently the documentation service triggered an incorrect build overnight. Until we fix that you can browse the latest version of the docs from the master branch: http://docs.docker.io/en/master

Quick update: until we figure out what broke the build on our ReadTheDocs.org setup, we switched the default branch to master. So if you visit http://docs.docker.io you will get the bleeding edge build of the documentation, which happens to be accurate since we released it this morning :)

Sorry about that. One more lesson learned on our quest to ultimate quality!

The Arch Linux instructions are still wrong; they say that aufs3 is required but it isn't anymore. http://docs.docker.io/en/master/installation/archlinux/

Is the warning "This is a community contributed installation path. The only ‘official’ installation is using the Ubuntu installation path. This version may be out of date because it depends on some binaries to be updated and published." still true? Fedora also has this warning (and no instructions). The "Look for your favorite distro in our installation docs!" link does not give me up-to-date instructions for any of my favorite Linux distros. I can't even see where in that installation documentation it says how to install from source code on generic Linux. What am I missing? (Of course I can get the source code and build it, but I want the documentation to be great :-D)

You're right, the arch docs need some updating. Pushing that to the queue. Thanks!

Yay! You should have have a section on installing from source too. This is part of doing open-source well.

We explain how to setup a dev and build environment here: http://docs.docker.io/en/latest/contributing/devenvironment/

I guess we could reference that it the install docs.
