# How and Why Do I Connect My AWS CUR to Archera?

Archera leverages the AWS Cost and Usage Report to accurately report on cloud costs inclusive of all other discount programs. By integrating with your CUR, we can provide the most accurate cost information and forecasts.

## Setup Options

When connecting to the CUR, customers have two options depending on whether they have an existing CUR defined within AWS:

* **No existing CUR:** Archera will automatically create one as part of the onboarding process and use it.
* **Existing CUR:** It is preferable to connect to the already existing CUR to be able to report on historical costs.

## Connecting to an Existing CUR

1. Navigate to the Archera Settings → Integrations Page: <https://app.archera.ai/settings/integrations>
2. Review Integrations at the bottom of the screen and look for **"Warnings Detected"**
3. Click on the Integration with the Warning Detected
4. Look for a notification that says **"Please Connect CUR:"**
5. Click **"Connect"** and follow the in-app walkthrough to apply the IAM policy to the Archera IAM role for the appropriate CUR
6. Click **"Verify Access"** at the bottom to confirm
