-## GCS Remote
-
-1. Create a [Service Account](https://cloud.google.com/iam/docs/service-accounts-create) named tofu (after enabling the
-   IAM API if needed). Leave the permissions blank.
-2. Create and download the [service account key](https://cloud.google.com/iam/docs/keys-create-delete#creating).
-3. Create a GCS bucket for tofu state with public access prevention and versioning as necessary.
-4. In the permissions tab of the bucket, give **Storage Object Admin** access to the service account.
-5. Copy backend.tf.sample to backend.tf and make necessary changes.
-
-```shell
-cp remote_backend.tf.sample remote_backend.tf

-### Encryption key
-
-Generate the encryption key
-
-```shell
-python3 -c 'import os;import base64;print(base64.b64encode(os.urandom(32)).decode("utf-8"))'
-```
-
-`Without the encryption key, your state would not be recoverable. Store in a password manager, if not using any kms like bws.`
-
-### Environment variables
-
-```shell
-export GOOGLE_APPLICATION_CREDENTIALS="<YOUR_DOWNLOADED_KEY_PATH>"
-export GOOGLE_ENCRYPTION_KEY="<YOUR_GENERATED_ENCRYPTION_KEY>"
-```
-
-Run tofu init / plan / apply as usual.
-
-### Bitwarden Secrets Manager
-
-Store the downloaded key contents and generated encryption key into GOOGLE_CREDENTIALS and GOOGLE_ENCRYPTION_KEY
-respectively in bws.
-
-Run bws run -- tofu init / plan / apply as usual.
-
-### Beta Notice
-
-`Please treat this as beta and only use for air-gapped installations as of now. Will remove the beta tag after testing it in due course.`
