Developing against Ionic locally

Hi,

I would like to develop against the latest master of ionic, however, the documentation seems to be outdated. (https://github.com/driftyco/ionic/blob/master/scripts/README.md)

After doing git clone and npm install --typecheck, I can’t build as there is no longer a gulp task named “package”. I found the build task, but when I try “gulp compile.release” I get the following errors:

[13:26:54] Using gulpfile D:\source\ionic2\ionicframework\gulpfile.js [13:26:54] Starting 'compile.release'...

What is the correct process for developing against the latest version of ionic?
