# Inventory The Inventory section of the RAPT Portal is designed to allow you to manage your own inventory of ingredients. It is a useful tool but it is not required in order to use the Recipe Editor. The RAPT Portal has a built in and up to date database of ingredients. Thus, you may use the Inventory feature purely to add your own, unlisted ingredients (in order to use them in recipes). It is also useful to record and track your personal inventory of ingredients so that you can see at a glance what ingredients you have to hand. When brewing recipes in the RAPT Portal, you can elect to automatically deduct the ingredients from your inventory thus it can be automatically kept up to date! There are seperate **Inventory** sections for [**Fermentables**](/inventory/fermentables.md), [**Hops**](/inventory/hops.md), [**Miscs**](/inventory/miscs.md) and [**Yeasts**](/inventory/yeasts.md) Items can be added to your inventory manually or imported from the database. Any item in your inventory can then be edited if required. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
