Getting started with building an app can be done by either starting from scratch or copying a pre-existing sample app.
To start from scratch, login to the builder and click on the + sign to create a new app. Give your app a name and optional description. You'll be directed to the app page and can now start building your data structure and designing your pages. It's that simple!
To use a pre-existing app, start by going to https://tadabase.io/samples, find the app you wish to start with, and click "Copy App". Give the app a unique name and you're good to go!
