+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.
+

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

+The wireguard service creates a secure mesh network between clan machines using two roles:

 ### IPv6 Address Allocation
-
-- Base network: `/40` ULA prefix (deterministically generated from instance
-  name)
+- Base network: `/40` ULA prefix (deterministically generated from instance name)
 - Controllers: Each gets a `/56` subnet from the base `/40`
-- Peers: Each gets a unique 64-bit host suffix that is used in ALL controller
-  subnets
+- Peers: Each gets a unique 64-bit host suffix that is used in ALL controller subnets
 
 ### Addressing Design
-
 - Each peer generates a unique host suffix (e.g., `:8750:a09b:0:1`)
-- This suffix is appended to each controller's `/56` prefix to create unique
-  addresses
+- This suffix is appended to each controller's `/56` prefix to create unique addresses
 - Example: peer1 with suffix `:8750:a09b:0:1` gets:

   - `fd51:19c1:c1:aa00:8750:a09b:0:1` in controller2's subnet
 - Controllers allow each peer's `/96` subnet for routing flexibility
 
 ### Connectivity
-

-  subnet)
-- Controllers connect to ALL other controllers and ALL peers on a single
-  interface
+- Peers use a single WireGuard interface with multiple IPs (one per controller subnet)

-  are always executed as part of the python module import logic and thus should
-  be as small as possible. i.e. `from clan_cli.vars.generators import ...`

 ## 💡 Tips for Working with clanServices
 
-- 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.

-Each test consists of an `expr` (expression) and an `expected` field. `nix-unit`
-simply checks if `expr == expected` and prints the diff if that's not the case.
