Curators are responsible for adding items and building pages. They are unable to create and or configure exhibits. It is not required that these steps be followed in order, but many steps build on prior ones (for instance, you cannot tag or create browse categories when you have not added any items). It is best practice to go through each step to ensure your exhibit is fully functional.
Your dashboard is the page from which you will navigate to all the areas to build your exhibit. The sidebar on the left-hand side of the screen is where you will find the pages to add content to your exhibit. You will return to this sidebar throughout the curation process.
