After you have correctly set up your development environment, you are ready to start building and testing your Ionic app.
There are a number of ways to run an Ionic app, however, it's recommended to start running it in the browser. To develop and test ionic apps on devices and emulators, see the Running an App Guide.
The majority of Ionic app development can be spent right in the browser using the
ionic serve command:
$ cd myApp$ ionic serve
This will open a local development server on your browser.
