Publish an app

- [Instructor] I want to tell you about this Publish button.…The first time I saved this app, it was published.…It wasn't published publicly for other people.…It was published and I'm really the only user of this app.…But if I wish at this point,…I could share this app with other people.…That's available to me.…Once I have people using my app, this Publish button…becomes more important to me because I might have people…who are using the app and I want to update it,…but I want to wait until I make sure that all of the updates…that I've created have been tested and I'm ready…to push this new version out to my users.…

If I click See all versions, it actually takes me…to a page that looks like this.…Here are the versions.…Right now, if I had shared Version 1 with other users,…they would be using it.…In the meantime, I have done several edits.…If I wish, then, to publish Version 5,…notice that I can choose it here…and click Publish this version.…This is also how you'd roll back to a prior version,…to Version 4, for example, if you wanted to restore it.…
