-This service sets up a certificate authority (CA) that can issue certificates to
-other machines in your clan. For this the `ca` role is used.
-It additionally provides a `default` role, that can be applied to all machines
-in your clan and will make sure they trust your CA.
-
-## Example Usage
-
-The following configuration would add a CA for the top level domain `.foo`. If
-the machine `server` now hosts a webservice at `https://something.foo`, it will
-get a certificate from `ca` which is valid inside your clan. The machine
-`client` will trust this certificate if it makes a request to
-`https://something.foo`.
-
-This clan service can be combined with the `coredns` service for easy to deploy,
-SSL secured clan-internal service hosting.

-This module enables hosting clan-internal services easily, which can be resolved
-inside your VPN. This allows defining a custom top-level domain (e.g. `.clan`)
-and exposing endpoints from a machine to others, which will be
-accessible under `http://<service>.clan` in your browser.
-
-The service consists of two roles:
-
-- A `server` role: This is the DNS-server that will be queried when trying to
-  resolve clan-internal services. It defines the top-level domain.
-- A `default` role: This does two things. First, it sets up the nameservers so
-  thatclan-internal queries are resolved via the `server` machine, while
-  external queries are resolved as normal via DHCP. Second, it allows exposing
-  services (see example below).
-
-## Example Usage
-
-Here the machine `dnsserver` is designated as internal DNS-server for the TLD
-`.foo`. `server01` will host an application that shall be reachable at
-`http://one.foo` and `server02` is going to be reachable at `http://two.foo`.
-`client` is any other machine that is part of the clan but does not host any
-services.
-
-When `client` tries to resolve `http://one.foo`, the DNS query will be
-routed to `dnsserver`, which will answer with `192.168.1.3`. If it tries to
-resolve some external domain (e.g. `https://clan.lol`), the query will not be
-routed to `dnsserver` but resolved as before, via the nameservers advertised by
-DHCP.

+This service generates the `system.stateVersion` of the nixos installation
+automatically.
+
+Possible values:
+[system.stateVersion](https://search.nixos.org/options?channel=unstable&show=system.stateVersion&from=0&size=50&sort=relevance&type=packages&query=stateVersion)
+
+## Usage
+
+The following configuration will set `stateVersion` for all machines:
+
+```
+inventory.instances = {
+  state-version = {
+    module = {
+      name = "state-version";
+      input = "clan";
+    };
+    roles.default.tags.all = { };
+  };
+```
+
+## Migration
+
+If you are already setting `system.stateVersion`, either let the automatic
+generation happen, or trigger the generation manually for the machine. The
+service will take the specified version, if one is already supplied through the
+config.
+
+To manually generate the version for a specified machine run:
+
+```
+clan vars generate [MACHINE]
+```
+
+If the setting was already set, you can then remove `system.stateVersion` from
+your machine configuration. For new machines, just import the service as shown
+above.

-## Migration from `root-password` module
-
-The deprecated `clan.root-password` module has been replaced by the `users` module. Here's how to migrate:
-
-### 1. Update your flake configuration
-
-Replace the `root-password` module import with a `users` service instance:
-
-```nix
-# OLD - Remove this from your nixosModules:
-imports = [
-  self.inputs.clan-core.clanModules.root-password
-];
-
-# NEW - Add to inventory.instances or machines/flake-module.nix:
-instances = {
-  users-root = {
-    module.name = "users";
-    module.input = "clan-core";
-    roles.default.tags.nixos = { };
-    roles.default.settings = {
-      user = "root";
-      prompt = false;  # Set to true if you want to be prompted
-      groups = [ ];
-    };
-  };
-};
-```
-
-### 2. Migrate vars
-
-The vars structure has changed from `root-password` to `user-password-root`:
-
-```bash
-# For each machine, rename the vars directories:
-cd vars/per-machine/<machine-name>/
-mv root-password user-password-root
-mv user-password-root/password-hash user-password-root/user-password-hash
-mv user-password-root/password user-password-root/user-password
-```

-This module sets up [yggdrasil](https://yggdrasil-network.github.io/) across
-your clan. 
-
-Yggdrasil is designed to be a future-proof and decentralised alternative to
-the structured routing protocols commonly used today on the internet. Inside
-your clan, it will allow you reaching all of your machines.
-
-## Example Usage
-
-While you can specify statically configured peers for each host, yggdrasil does
-auto-discovery of local peers.
-
-```nix
-inventory = {
-
-  machines = {
-    peer1 = { };
-    peer2 = { };
-  };
-
-  instances = {
-    yggdrasil = {

+---
+
+## Override Example
 
 Example of instantiating a `borgbackup` service using `clan-core`:
 
 ```nix
 inventory.instances = {
-
-    borgbackup = { # <- Instance name
-
-        # This can be partially/fully specified,
-        # - If the instance name is not the name of the module
-        # - If the input is not clan-core
-        # module =  {
-        #     name = "borgbackup";  # Name of the module (optional)
-        #     input = "clan-core"; # The flake input where the service is defined (optional)
-        # };
-
+    # Instance Name: Different name for this 'borgbackup' instance
+    borgbackup = {
+        # Since this is instances."borgbackup" the whole `module = { ... }` below is equivalent and optional.
+        module =  {
+            name = "borgbackup";  # <-- Name of the module (optional)
+            input = "clan-core"; # <-- The flake input where the service is defined (optional)
+        };
         # Participation of the machines is defined via roles
+        # Right side needs to be an attribute set. Its purpose will become clear later
         roles.client.machines."machine-a" = {};
         roles.server.machines."backup-host" = {};
     };
 }
 ```
 
-## Module Settings
+If you used `clan-core` as an input attribute for your flake:
 
-Each role might expose configurable options. See clan's [clanServices
-reference](../reference/clanServices/index.md) for all available options.
+```nix
+      # ↓ module.input = "clan-core"
+inputs.clan-core.url = "https://git.clan.lol/clan/clan-core/archive/main.tar.gz";
+```
 
-Settings can be set in per-machine or per-role. The latter is applied to all
-machines that are assigned to that role.
+## Simplified Example
 
+If only one instance is needed for a service and the service is a clan core service, the `module` definition can be omitted.
+
+```nix
+# Simplified way of specifying a single instance
+inventory.instances = {
+    # instance name is `borgbackup` -> clan core module `borgbackup` will be loaded.
+    borgbackup = {
+        # Participation of the machines is defined via roles
+        # Right side needs to be an attribute set. Its purpose will become clear later
+        roles.client.machines."machine-a" = {};
+        roles.server.machines."backup-host" = {};
+    };
+}
+```
+
+## Configuration Example
+
+Each role might expose configurable options
+
+See clan's [clanServices reference](../reference/clanServices/index.md) for available options
 
 ```nix
 inventory.instances = {
-    borgbackup = {
-        # Settings for 'machine-a'
+    borgbackup-example = {
+        module =  {
+            name = "borgbackup";
+            input = "clan-core";
+        };
         roles.client.machines."machine-a" = {
+            # 'client' -Settings of 'machine-a'
             settings = {
                 backupFolders = [
                     /home
                     /var
                 ];
             };
+            # ---------------------------
         };
-
-        # Settings for all machines of the role "server"
-        roles.server.settings = {
-            directory = "/var/lib/borgbackup";
-        };
+        roles.server.machines."backup-host" = {};
     };
 }
 ```
 
 ## Tags
 
-Tags can be used to assign multiple machines to a role at once. It can be thought of as a grouping mechanism.
-
-For example using the `all` tag for services that you want to be configured on all
-your machines is a common pattern.
-
-The following example could be used to backup all your machines to a common
-backup server
+Multiple members can be defined using tags as follows
 
 ```nix
 inventory.instances = {
-    borgbackup = {
-        # "All" machines are assigned to the borgbackup 'client' role
-        roles.client.tags =  [ "all" ];
-
-        # But only one specific machine (backup-host) is assigned to the 'server' role
-        roles.server.machines."backup-host" = {};
-    };
-}
-```
-
-## Sharing additional Nix configuration
-
-Sometimes you need to add custom NixOS configuration alongside your clan
-services. The `extraModules` option allows you to include additional NixOS
-configuration that is applied for every machine assigned to that role.
-
-There are multiple valid syntaxes for specifying modules:
-
-```nix
-inventory.instances = {
-    borgbackup = {
-        roles.client = {
-            # Direct module reference
-            extraModules = [ ../nixosModules/borgbackup.nix ];
-
-            # Or using self (needs to be json serializable)
-            # See next example, for a workaround.
-            extraModules = [ self.nixosModules.borgbackup ];
-
-            # Or inline module definition, (needs to be json compatible)
-            extraModules = [
-              {
-                # Your module configuration here
-                # ...
-                #
-                # If the module needs to contain non-serializable expressions:
-                imports = [ ./path/to/non-serializable.nix ];
-              }
-            ];

-- You can add multiple inputs to your flake (`clan-core`, `your-org-modules`, etc.) to mix and match services.
-- Each service instance is isolated by its key in `inventory.instances`, allowing to deploy multiple versions or roles of the same service type.

-
-### How It Works
-
-Clan automatically tries networks in order of priority:
-1. Direct internet connections (if configured)
-2. VPN networks (ZeroTier, Tailscale, etc.)
-3. Tor hidden services
-4. Any other configured networks
-
-If one network fails, Clan automatically tries the next.
-
-### Useful Commands
-
-```bash
-# View all configured networks and their status
-clan network list
-
-# Test connectivity through all networks
-clan network ping machine1
-
-# Show complete network topology
-clan network overview
-```
-
-## Option 2: Manual targetHost (Bypasses Fallback!)
-
-!!! warning
-    Setting `targetHost` directly **disables all automatic networking and fallback**. Only use this if you need complete control and don't want Clan's intelligent connection management.
-
-### Using Inventory (For Static Addresses)
-
-Use inventory-level `targetHost` when the address is **static** and doesn't depend on NixOS configuration:
-
-```{.nix title="flake.nix" hl_lines="8"}
-{
-  outputs = { self, clan-core, ... }:
-    let
-      clan = clan-core.lib.clan {
-        inventory.machines.server = {
-          # WARNING: This bypasses all networking modules!
-          # Use for: Static IPs, DNS names, known hostnames
-          deploy.targetHost = "root@192.168.1.100";
-        };
-      };
-    in
-    {
-      inherit (clan.config) nixosConfigurations;
-    };
-}
-```
-
-**When to use inventory-level:**
-- Static IP addresses: `"root@192.168.1.100"`
-- DNS names: `"user@server.example.com"`
-- Any address that doesn't change based on machine configuration
-
-### Using NixOS Configuration (For Dynamic Addresses)
-
-Use machine-level `targetHost` when you need to **interpolate values from the NixOS configuration**:
-
-```{.nix title="flake.nix" hl_lines="7"}
-{
-  outputs = { self, clan-core, ... }:
-    let
-      clan = clan-core.lib.clan {
-        machines.server = { config, ... }: {
-          # WARNING: This also bypasses all networking modules!
-          # REQUIRED for: Addresses that depend on NixOS config
-          clan.core.networking.targetHost = "root@${config.networking.hostName}.local";
-        };
-      };
-    in
-    {
-      inherit (clan.config) nixosConfigurations;
-    };
-}
-```
-
-**When to use machine-level (NixOS config):**
-- Using hostName from config: `"root@${config.networking.hostName}.local"`
-- Building from multiple config values: `"${config.users.users.deploy.name}@${config.networking.hostName}"`
-- Any address that depends on evaluated NixOS configuration
-
-!!! info "Key Difference"
-    **Inventory-level** (`deploy.targetHost`) is evaluated immediately and works with static strings.
-    **Machine-level** (`clan.core.networking.targetHost`) is evaluated after NixOS configuration and can access `config.*` values.
-
-## Quick Decision Guide
-
-| Scenario | Recommended Approach | Why |
-|----------|---------------------|-----|
-| Public servers | `internet` service | Keeps fallback options |
-| Mixed infrastructure | Multiple networks | Automatic failover |
-| Machines behind NAT | ZeroTier/Tor | NAT traversal with fallback |
-| Testing/debugging | Manual targetHost | Full control, no magic |
-| Single static machine | Manual targetHost | Simple, no overhead |
-
-## Command-Line Override
-
-The `--target-host` flag bypasses ALL networking configuration:
-
-```bash
-# Emergency access - ignores all networking config
-clan machines update server --target-host root@backup-ip.com
-
-# Direct SSH - no fallback attempted
-clan ssh laptop --target-host user@10.0.0.5
-```
-
-Use this for debugging or emergency access when automatic networking isn't working.

+# How to Set `targetHost` for a Machine
+
+The `targetHost` defines where the machine can be reached for operations like SSH or deployment. You can set it in two ways, depending on your use case.
+
+---
+
+## ✅ Option 1: Use the Inventory (Recommended for Static Hosts)
+
+If the hostname is **static**, like `server.example.com`, set it in the **inventory**:
+
+```{.nix title="flake.nix" hl_lines="8"}
+{
+  # edlided
+  outputs =
+    { self, clan-core, ... }:
+    let
+      # Sometimes this attribute set is defined in clan.nix
+      clan = clan-core.lib.clan {
+        inventory.machines.jon = {
+            deploy.targetHost = "root@server.example.com";
+        };
+      };
+    in
+    {
+      inherit (clan.config) nixosConfigurations nixosModules clanInternals;
+      # elided
+    };
+}
+```
+
+This is fast, simple and explicit, and doesn’t require evaluating the NixOS config. We can also displayed it in the clan-cli or clan-app.
+
+---
+
+## ✅ Option 2: Use NixOS (Only for Dynamic Hosts)
+
+If your target host depends on a **dynamic expression** (like using the machine’s evaluated FQDN), set it inside the NixOS module:
+
+```{.nix title="flake.nix" hl_lines="8"}
+{
+  # edlided
+  outputs =
+    { self, clan-core, ... }:
+    let
+      # Sometimes this attribute set is defined in clan.nix
+      clan = clan-core.lib.clan {
+        machines.jon = {config, ...}: {
+            clan.core.networking.targetHost = "jon@${config.networking.fqdn}";
+        };
+      };
+    in
+    {
+      inherit (clan.config) nixosConfigurations nixosModules clanInternals;
+      # elided
+    };
+}
+```
+
+Use this **only if the value cannot be made static**, because it’s slower and won't be displayed in the clan-cli or clan-app yet.
+
+---
+
+## 📝 TL;DR
+
+| Use Case                  | Use Inventory? | Example                          |
+| ------------------------- | -------------- | -------------------------------- |
+| Static hostname           | ✅ Yes          | `root@server.example.com`        |
+| Dynamic config expression | ❌ No           | `jon@${config.networking.fqdn}` |
+
+---
+
+## 🚀 Coming Soon: Unified Networking Module
+
+We’re working on a new networking module that will automatically do all of this for you.
+
+- Easier to use
+- Sane defaults: You’ll always be able to reach the machine — no need to worry about hostnames.
+- ✨ Migration from **either method** will be supported and simple.
+
+## Summary
+
+- Ask: *Does this hostname dynamically change based on NixOS config?*
+- If **no**, use the inventory.
+- If **yes**, then use NixOS config.
