If you’ve installed the needed prerequisites from the previous section, then in order to install Ionic (both on Mac and Windows) you just have to run the following command:

npm install ionic cordova -g

Ionic uses [Cordova](https://cordova.apache.org/) in the background for packaging up the native app, thus the need for it. We’re using the **-g** flag here, in order to install the packages **ionic** and **cordova**.

To verify that you’ve installed Ionic correctly on your Windows/Mac machine, run the following command in your Command prompt/Terminal:

ionic -v

You should get an output similar to:

3.4.0

To verify that you’ve installed Cordova correctly on your Windows/Mac machine, run the following command in your Command prompt/Terminal:

cordova -v

You should get an output similar to:

7.0.1
