+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.
+

-
-If you are already setting `system.stateVersion`, either let the automatic

-
-To manually generate the version for a specified machine run:
-
-```

-above.

+## Module Settings

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

 ## 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 = {
+    borgbackup = {
-        module =  {
+        # "All" machines are assigned to the borgbackup 'client' role
-            name = "borgbackup";
+        roles.client.tags =  [ "all" ];
-            input = "clan-core";
+
-        };
+        # But only one specific machine (backup-host) is assigned to the 'server' role
-        #
-        # The 'all' -tag targets all machines
-        roles.client.tags."all" = {};
-        # ---------------------------
         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 ];
+              }
+            ];
+        };
