+# Turn a Cloud at Cost CentOS-7-64bit server into NixOS
+
+1. Configure the system (`$systemname`) you'd like to install (see Configuration below).
+2. Create new server instance (either Custom or cloudpro) using "CentOS-7-64bit".
+ Note the servername (something like c731445864-cloudpro-388922936).
+3. `cac_login=xxx cac_key=yyy ./infest-cac-CentOS-7-64bit.sh servername:$servername $systename`
+4. Enjoy. (`ssh root@$systename`)
+
+# Configuration
+
+Configure your system in modules/$systemname
+See modules/cd/default.nix as an example.
+
+Notice that modules/$systemname/networking will be autogenerated (but not committed).
+
+secrets/$systemname/nix/foo can be accessed as `<secrets/foo>` from within the configuration.
+
+You might want `secrets/$systemname/rsync/etc/tinc/retiolum/rsa_key.priv`.
+
+You might want `secrets/$systemname/nix/hashedPasswords.nix`, which looks like
+
+```nix
+_: { users.extraUsers.root.hashedPassword = "XXX"; }
+```
+
+`XXX` can be generated with e.g.
+
+```
+mkpasswd -m sha-512 -S $(openssl rand -base64 16 | tr -d '+=' | head -c 16)
+```
