# Creating add-ons

To create an add-on:

1. Click the **"+ Add"** button under the **Add-ons** section of the selected product.
2. In the modal that opens, enter the following details:
   1. **Name**: the name of the add-on.
   2. **ID**: automatically generated by Stigg. Use this ID to reference the add-on in your application. To link an existing add-on, override the auto-generated value.
   3. **Description (optional)**: a short description of the add-on.
   4. **Add-on type**: choose one of the following:
      * **Single instance**: customers’ subscriptions can include only one instance of this add-on. Useful for features like single sign-on (SSO) or premium support.
      * **Multiple instance**: customers’ subscriptions can include multiple instances of this add-on. Useful for features like additional API calls or extra credits.

<Note>
  The values entered in the “Name” and “Description” fields are displayed in the customer-facing paywall and customer portal. Use customer-friendly text.
</Note>

3. Click **"Create"** to confirm.
4. Review the newly created add-on, which is initially saved as a draft.
5. Publish the add-on to make it visible to customers and available for inclusion in subscriptions.

<Warning>
  Before publishing an add-on, make sure to [assign features](#assigning-features-to-add-ons) and define its [pricing](#defining-the-add-ons-price).
