+# Quick start
+
+## How to create files for a new zone
+
+*The documentation is written for the production cluster, the same apply for other clusters.*
+
+Basically:
+  - Create your `site` file in `cluster/prod/site/` folder
+  - Create your `node` files in `cluster/prod/node/` folder
+  - Add your wireguard configuration to `cluster/prod/cluster.nix`
+    - You will have to edit your NAT config manually to bind one public IPv4 port to each node
+    - Nodes' public wireguard keys are generated during the first run of `deploy_nixos`, see below
+  - Add your nodes to `cluster/prod/ssh_config`, it will be used by the various SSH scripts.
+    - If you use `ssh` directly, use `ssh -F ./cluster/prod/ssh_config`
+    - Add `User root` for the first time as your user will not be declared yet on the system
+
+## How to deploy a Nix configuration on a fresh node
+
+We suppose that the node name is `datura`. 
+Start by doing the deployment one node at a time, you will have plenty of time
+in your operator's life to break everything through automation.
+
+Run:
+  - `./deploy_nixos prod datura` - to deploy the nix configuration file;
+   - a new wireguard key is printed if it hadn't been generated before, it has to be
+     added to `cluster.nix`, and then redeployed on all nodes as the new wireguard conf is needed everywhere
+  - `./deploy_passwords prod datura` - to deploy user's passwords
+   - if a user changes their password (using `./passwd`), needs to be redeployed on all nodes to setup the password on all nodes
+  - `./deploy_pki prod datura` - to deploy Nomad's and Consul's PKI
