For steps on how to setup the Native Version, you can visit Create Your First Mag Issue
The Native Version is the Text Version of your issue.
It is the quickest way to setup and publish issues for your app.
Images can be uploaded directly into your articles, which is helpful if you want to add
Full Page Adverts between articles.
A table of contents page is not needed inside your issue, as the table of contents is automatically generated for you.
It is not necessary to upload a cover image since the cover of the issue is already displayed on the homescreen of the app.
If you do want to add the cover image you can upload it as a full page image in a blank article, then set it as the first article of your issue.
