+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.
+
+```nix
+inventory = {
+

-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.

 ## Module source specification
 
-Each instance includes a reference to a **module specification** — this is how Clan knows which service module to use and where it came from.

+## Module Settings
+
+Each role might expose configurable options. See clan's [clanServices

+Settings can be set in per-machine or per-role. The latter is applied to all

-
-If only one instance is needed for a service and the service is a clan core service, the `module` definition can be omitted.

-```
-

-Each role might expose configurable options
-
-See clan's [clanServices reference](../reference/clanServices/index.md) for available options
-
-```nix
-inventory.instances = {
-    borgbackup-example = {
-        module =  {
-            name = "borgbackup";
-            input = "clan-core";
-        };
+        # Settings for 'machine-a'
         roles.client.machines."machine-a" = {

                 backupFolders = [
                     /home
                     /var
                 ];
             };

+        # Settings for all machines of the role "server"
+        roles.server.settings = {
+            directory = "/var/lib/borgbackup";
+        };
     };
 }
 ```
 
 ## Tags
 
-Multiple members can be defined using tags as follows
+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
 
 ```nix
 inventory.instances = {
-    borgbackup-example = {
-        module =  {
-            name = "borgbackup";
-            input = "clan-core";
-        };
-        #
-        # The 'all' -tag targets all machines
-        roles.client.tags."all" = {};
-        # ---------------------------
+    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 you to deploy multiple versions or roles of the same service type.
-* Roles can target different machines or be scoped dynamically.

+# Connecting to Your Machines
+
+Clan provides automatic networking with fallback mechanisms to reliably connect to your machines.
+
+## Option 1: Automatic Networking with Fallback (Recommended)
+
+Clan's networking module automatically manages connections through various network technologies with intelligent fallback. When you run `clan ssh` or `clan machines update`, Clan tries each configured network by priority until one succeeds.
+
+### Basic Setup with Internet Service
+
+For machines with public IPs or DNS names, use the `internet` service to configure direct SSH while keeping fallback options:
+
+```{.nix title="flake.nix" hl_lines="7-10 14-16"}
+{
+  outputs = { self, clan-core, ... }:
+    let
+      clan = clan-core.lib.clan {
+        inventory.instances = {
+          # Direct SSH with fallback support
+          internet = {
+            roles.default.machines.server1 = {
+              settings.address = "server1.example.com";
+            };
+            roles.default.machines.server2 = {
+              settings.address = "192.168.1.100";
+            };
+          };
+
+          # Fallback: Secure connections via Tor
+          tor = {
+            roles.server.tags.nixos = { };
+          };
+        };
+      };
+    in
+    {
+      inherit (clan.config) nixosConfigurations;
+    };
+}
+```
+
+### Advanced Setup with Multiple Networks
+
+```{.nix title="flake.nix" hl_lines="7-10 13-16 19-21"}
+{
+  outputs = { self, clan-core, ... }:
+    let
+      clan = clan-core.lib.clan {
+        inventory.instances = {
+          # Priority 1: Try direct connection first
+          internet = {
+            roles.default.machines.publicserver = {
+              settings.address = "public.example.com";
+            };
+          };
+
+          # Priority 2: VPN for internal machines
+          zerotier = {
+            roles.controller.machines."controller" = { };
+            roles.peer.tags.nixos = { };
+          };
+
+          # Priority 3: Tor as universal fallback
+          tor = {
+            roles.server.tags.nixos = { };
+          };
+        };
+      };
+    in
+    {
+      inherit (clan.config) nixosConfigurations;
+    };
+}
+```
+
+### 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.

+## Example: A machine-type service
+
+Users often have different types of machines. These could be any classification
+you like, for example "servers" and "desktops". Having such distictions, allows
+reusing parts of your configuration that should be appplied to a class of
+machines. Since this is such a common pattern, here is how to write such a
+service.
+
+For this example the we have to roles: `server` and `desktop`. Additionally, we
+can use the `perMachine` section to add configuration to all machines regardless
+of their type.
+
+```nix title="machine-type.nix"
+{
+  _class = "clan.service";
+  manifest.name = "machine-type";
+
+  roles.server.perInstance.nixosModule = ./server.nix;
+  roles.desktop.perInstance.nixosModule = ./desktop.nix;
+
+  perMachine.nixosModule = {
+    # Configuration for all machines (any type)
+  };
+}
+
+```
+
+In the inventory we the assign machines to a type, e.g. by using tags
+
+```nix title="flake.nix"
+instnaces.machine-type = {
+  module.input = "self";
+  module.name = "@pinpox/machine-type";
+  roles.desktop.tags.desktop = { };
+  roles.server.tags.server = { };
+};
+```

-# 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.
