 Before deploying the deployable architecture, ensure you have:
 
-* Created an API key in the target account with sufficient permissions. The target account is the account that will be hosting the resources deployed by this deployable architecture. See [instructions](https://cloud.ibm.com/docs/account?topic=account-userapikey&interface=ui) Note the API key, as it will be used later. On evaluation environments, you may simply grant `Administrator` role on `IAM Identity Service`, `All Identity and Access enabled services` and `All Account Management` services. If you need to narrow down further access, for a production environment for instance, the minimum level of permissions is indicated in the [Permission tab](https://cloud.ibm.com/catalog/7df1e4ca-d54c-4fd0-82ce-3d13247308cd/architecture/Retrieval_Augmented_Generation_Pattern-5fdd0045-30fc-4013-a8bc-6db9d5447a52?kind=terraform&format=stack&version=32db3936-66fe-4b04-bbc8-61d5676a89f1#permissions) of the deployable architecture.

 * (Recommended to ensure successful sample app deployment) Created or have access to a signing key, which is the base64 key obtained from `gpg --gen-key` (if not generated before or expired) and then exported via `gpg --export-secret-key <Email Address> | base64` command. See the [devsecops image signing page](https://cloud.ibm.com/docs/devsecops?topic=devsecops-devsecops-image-signing#cd-devsecops-gpg-export) for details. Keep note of the key for later. The signing key is not required to deploy all of the Cloud resources created by this deployable architecture, but is necessary to get the automation to build and deploy the sample application.
 * (Optional) Installed the IBM Cloud CLI's Project add-on using the `ibmcloud plugin install project` command. More information is available [here](https://cloud.ibm.com/docs/cli?topic=cli-projects-cli).
