How to update app


First time writing here. I feel so dumb, cause I have done a UI with Ionic Creator. I am using Atom and have opened the project that was downloaded from Ionic Creator in Atom. I am using a plugin in Atom that is named Ionic Preview. The problem is now that the page that is showed is the regular page. Like I have not done anything. My question is now… How do I update?

I am a useless programmer and have hard to find and see different ways of solve such problems, though I read languages as Java, C#, SQL and JavaBeans. I use Mac.

Do you guys have tip and guidelines for ionic? I feel that ionics one website is quite hard too understand.

Kind regards.
