 This will force the recording files to be deleted before running the tests.
 
-To be able to run the tests in recording or live mode, make sure:
-
-- You have a client app registered in Microsoft Entra ID (formerly Azure Active Directory)
-- The client app is configured with [certificate-based authentication](https://learn.microsoft.com/en-us/entra/identity/authentication/how-to-certificate-based-authentication)
-- The client app has "Contributor" permissions to your Azure Quantum Workspace
-- The following environment variables are set:  
-  - `AZURE_CLIENT_ID` - application (client) ID from Microsoft Entra ID
-  - `AZURE_TENANT_ID` - directory (tenant) ID from Microsoft Entra ID
-  - `AZURE_CLIENT_CERTIFICATE_PATH` - path to PEM or PKCS12 certificate file (including the private key) that is configured for the client app
-  - `AZURE_CLIENT_SEND_CERTIFICATE_CHAIN=True` - prompts Azure.Identity to set X5C header (specifying certificate chain) required to support SNI authentication

+- You have installed [Azure CLI](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest).
+- You're logged into your Azure Entra ID Tenant in the Azure CLI - `az login` (or `az login --tenant <tenantId>`).
+- You have "Quantum Workspace Owner" or "Quantum Workspace Data Contributor" or "Contributor" role on the Azure Quantum Workspace against which you would like to capture the recordings.
+- You have all necessary Providers added to the Azure Quantum Workspace.
+- The following environment variables are set:
   - `AZURE_QUANTUM_SUBSCRIPTION_ID` - ID of the Subscription where Azure Quantum Workspace is deployed
   - `AZURE_QUANTUM_WORKSPACE_RG` - name of the Resource Group where Azure Quantum Workspace is deployed
