-In this example, we demonstrate how to retrieve secrets from a project and environment using an Infisical Token.
-
 Prerequisites:
 
 - Set up and add envars to [Infisical Cloud](https://app.infisical.com).
 - Create an [Infisical Token](../../../getting-started/dashboard/token) for your project and environment.
 - Grasp a basic understanding of the system and its underlying cryptography [here](/api-reference/overview/introduction).
+- [Ensure that your project is blind-indexed](../blind-indices).
