Typescript demo compile errors

I’m going through the Ionic and Typescript part 1 demo, and when I “gulp compile” and get
the “Compiling Typescript files …” they are followed with tsc errors on app.ts
"Could not find symbol ‘angular’"
“Could not find symbol ‘cordova’”
“The property ‘cordova’ does not exist on value of type ‘Window’”

gulp-tsc using tsc version 1.0.3.0
ionic version 1.7.8
project is the tabs project, no mods other than those in the video (create /src with .js files renamed to .ts)
windows 10/webstorm 11

The solution is to bring down the ionic typescript mappings. This short video shows the process a guy goes through to do so for angular:


(remember to also tsd install ionic)
