Before building your app, you will need to create a Cordova Project locally on your machine.
To do this, navigate into the parent folder that will hold your Cordova project, and run the command:
Create
cordova create <nameOfCordovaAppFolder> <appID> <appName>
For example:
cordova create myCordovaApp io.blinkm.myapp myCordovaAppName
Note: Make sure you don't include dashes or special characters in your appID, as Cordova will reject them
This will create a new folder on your computer named "myCordovaApp". This is your Cordova "project root" folder.
