 ## Manage your GCP Keys for your service accounts
 
-The Anthos on Baremetal install requires several service accounts and keys to be created. See the [Google documentation](https://cloud.google.com/anthos/gke/docs/bare-metal/1.6/installing/install-prereq#service_accounts_prerequisites) for more details. By default, Terraform will create and manage these service accounts and keys for you (recommended). Alternatively, you can create these keys manually, or use a provided helper script to make the keys for you.

 If doing so manually, you must create each of these keys and place it in a folder named `keys` within the `util` folder.
-The service accounts also need to have IAM roles assigned to each of them. To do this manually, you'll need to follow the [instructions from Google](https://cloud.google.com/anthos/gke/docs/bare-metal/1.6/installing/install-prereq#service_accounts_prerequisites)

 Much easier (and recommended) is to use the helper script located in the `util` directory called `setup_gcp_project.sh` to create these keys and assign the IAM roles. The script will allow you to log into GCP with your user account and the GCP project for your Anthos cluster.
