Issue to connect app and don't know if the plugin has been added



I’m noob as programmer on application and someone advised me to used Ionic in order to do some trial.
The issue is I don’t think that my I successed to connect my app on ionic and I don’t know if the other plugin as cordova or git has been good installed on computer.

I need your help in order to do the best on that.

Could you please help me?
