+# Change Admins
+A Skynet Admin is a user with teh highest level of access to the cluster, having been trained up over a year.  
+This guide will cover adding and removing an Admin.
+
+The normal Committee Member process applies to them as well, so check [here](./committee_modify.md#adding) for teh specific details.
+
+A user cannot add or remove themselves from being an admin, an existing admin must do so (one who will still be admin after the procedure).
+
+## Add
+Steps to add a new Admin
+
+### NixOS
+There are several steps related to the NixOS repo on Forgejo.
+
+#### Username Added
+Like a normal committee member the users username must be added to the [``config/users.nix``][users.nix], specifically the admin section.  
+This gives teh user teh correct Skynet roles on our services.  
+This also enables them to use their personal account to login to all the servers.  
+
+#### SSH Key
+##### Root Account
+There is a ``root`` account that admins can use.  
+To be able to login as root you have to add you key to the keys for ``root``
+
+You can add it in the [``machines/_base.nix``][base.nix].
+
+##### Secrets Management
+We store our secrets encrypted in the repo using a tool called ``agenix``, a nix implementation of [age][age].  
+In order to create/edit any secret your key has to be added to [``secrets/secrets.nix``][secrets.nix].
+
+Add the key mimicking the format for the other admins.  
+Then add it to the users list/array.  
+Finally re-key the secrets
+
+
+###### Re-key Secrets
+In order to re-key the secrets your key must have been previously added (this just not work if you have just added your key, an existing admin must do this).  
+
+
+```shell
+# enter the devshell
+nix develop
+
+# Move into teh secrets folder
+cd secrets
+
+# Re-key the secrets
+agenix -R
+```
+
+Then commit the changes.
+
+### VPN
+The VPN is what allows admins to get access to the internal parts of teh cluster when not on campus.  
+It is provided by ITD.
+
+1. Add an entry to the bottom of [``ITD/VPN_Admins.csv``][VPN_Admins.csv]
+2. Add an entry to [``ITD/VPN_Admins_changes.csv``][VPN_Admins_changes.csv] with ``Pending`` for teh Action.
+3. Open up a TopDesk request with ITD to add the new Admin (TODO: TopDesk procedure)
+4. Add the ticket reference to [``ITD/VPN_Admins_changes.csv``][VPN_Admins_changes.csv]
+5. When complete mark the entry ``Added`` on [``ITD/VPN_Admins_changes.csv``][VPN_Admins_changes.csv].
+
+## Remove
+For teh most part the removal/retirement of an admin is just the opposite of the adding.  
+The main difference is contacting ITD to remove them from the VPN.
+
+### VPN
+1. Open up a TopDesk request with ITD to remove the old Admin.
+2. Add the ticket reference to [``ITD/VPN_Admins_changes.csv``][VPN_Admins_changes.csv]
+3. When complete mark the entry ``Removed`` on [``ITD/VPN_Admins_changes.csv``][VPN_Admins_changes.csv].
