-## sops
-
-We are sharing secrets using [`sops`](https://github.com/getsops/sops) and [`sops-nix`](https://github.com/Mic92/sops-nix)
-As of right now we use only `age` keys.
-The machine keys are derived from their server ssh keys, that they generate at first boot.
-User keys are generated by the users.
-New keys and machines need entries into the `.sops.yaml` file within the root directory of this repo.
-
-To make a secret available on a given machine you need to do the following. Configure the following keys
-
-```
-sops.secrets.example-key = {
-  sopsFile = "relative path to file in the repo containing the secrets (optional else the sops.defaultSopsFile is used)
-  path = "optinal path where the secret gets symlinked to, practical if some programm expects a specific path"
-  owner = user that owns the secret file: config.users.users.nerf.name (for example)
-  group = same as user just with groups: config.users.users.nerf.group
-  mode = "premission in usual octet: 0400 (for example)"
-```
-afterwards the secret should be available in `/run/secrets/example-key`.
-If the accessing process is not root it must be member of the group `config.users.groups.keys`
-for systemd services this can be archived by setting `serviceConfig.SupplementaryGroups = [ config.users.groups.keys.name ];`
-it the service config.
