## Add a resource

Each resource type has its own form. After you click **Add resources** and choose a type, Gapstack opens the fields for that type. You enter the details, then save. Gapstack adds the resource to the environment.

Cognito is one example. Its form collects the user pool and related settings. You do not fill a generic form and map it to AWS yourself.

<Steps>
  <Step title="Open Select Resources">
    Open the environment, then click **Add resources**.
  </Step>

  <Step title="Choose a type">
    Select a resource, such as **Cognito**. The right pane shows what that type provisions.
  </Step>

  <Step title="Complete the form">
    Enter the details for that resource, then click **Create**. Repeat for each type you need.
  </Step>
</Steps>

## Example: Add Cognito

The **Add Cognito** form collects the user pool, password policy, and configuration. Fill it in, then click **Create**. Gapstack adds the resource to the environment.
