After overcoming the slight disbelief that one still has to download firefox to read the (largely unchanged) help files, I've proceeded an attempt to launch 1.0. I'm stuck at "Provide App ID for Web App Builder" where you have to "manually register the Web AppBuilder in you portal [sic]".
In the "Tip" section, I'm told the vital piece of missing information: "During Web AppBuilder registration, you may input http://[yourmachinename]:3344/webappbuilder as URL of the app item." I do this, and the page comes back unchanged with the exception of a new red border around the App ID input box. No errors. No helpful messages. What am I missing?
