Sure! To set up your main categories and sub-categories in MongoDB, you will need to create a collection for each of your main categories first. Then, within each of these collections, you can create additional sub-collections for the related sub-categories. For example, if you have a main category called 'Clothing', you can create sub-collections for 'Shoes', 'Pants', 'Shirts', etc. Then, when you add items to each collection, you can assign a field called 'category' to the item so that you can track which items belong to which main and sub-categories.
