Hey yall!
Exciting times here at Ionic.
We just recently did a big switch in the github repo for ionic.
Starting now, the Ionic 2 codebase will be the master branch. 
The V1 version of ionic has moved to it’s own 1.X branch.
While this is very exciting, we are aware that some links may be broken for a short period of time.
We’re currently working on updating all the links.
If you find anything on the site that has 404’d or points to the incorrect place, please let me know so I can take care of it.
Cheers!
Mike
