 Add the secrets to Consul, near your service secrets.
 The idea is that the backuping service is a component of the global running service.
-You must add:
-  - `backup_aws_access_key_id`
-  - `backup_aws_secret_access_key`
-  - `backup_restic_repository`
-  - `backup_restic_password`
+You must run in `app/<name>/secrets/<subpath>`:
+
+```bash
+echo "USER Backup AWS access key ID" > backup_aws_access_key_id
+echo "USER Backup AWS secret access key" > backup_aws_secret_access_key
+echo "USER Restic repository, eg. s3:https://s3.garage.tld" > backup_restic_repository
+echo "USER Restic password to encrypt backups" > backup_restic_password
+```
+
+Then run secretmgr:
 
+```bash
+# Spawning a nix shell is an easy way to get all the dependencies you need
+nix-shell
+
+# Check that secretmgr works for you
+python3 secretmgr.py check <name>
+
+# Now interactively feed the secrets
+python3 secretmgr.py gen <name>
