Ionic + WebStorm on Windows

How can I setup WebStorm IDE on Windows, in order to properly develop Ionic apps? Right now, I have Node and WebStorm installed, but when I try to start an empty Project - and after install Cordova and Ionic via Terminal - it installs this Packages, but I cannot run ionic start command… It tells me that ionic is not recognized as an internal or external command… How can I fix this (while using a Local Installation strategy)? Thank you,
