 This module implements the Munin reporting protocol, allowing you to
 collect statistics directly from Prosody into Munin.
 
+Configuration
+=============
+
+There is only one recommended option, `munin_node_name`, which specifies
+the name that Prosody will identify itself by to the Munin server. You
+may want to set this to the same hostname as in the [SRV record][doc:dns]
+for the machine.
+
+```lua
+modules_enabled = {
+    -- your other modules
+    "munin",
+}
+
+munin_node_name = "xmpp.example.com"
+```
+
+
+## Summary
+
+All these must be in [the global section][doc:configure#overview].
+
+  Option                  Type     Default
+  ----------------------- -------- ---------------------------
+  munin\_node\_name       string   `"localhost"`
+  munin\_ignored\_stats   set      `{ }`
+  munin\_ports            set      `{ 4949 }`
+  munin\_interfaces       set      `{ "0.0.0.0", "::" }`[^1]
+
+[^1]: Varies depending on availability of IPv4 and IPv6
+
+## Ports and interfaces
+
+
+`mod_munin` listens on port `4949` on all local interfaces by default.
+This can be changed with the standard [port and network configuration][doc:ports]:
+
+
+``` lua
+-- defaults:
+munin_ports = { 4949 }
+munin_interfaces = { "::", "0.0.0.0" }
+```
+
+If you already have a `munin-node` instance running, you can set a
+different port to avoid the conflict.
+
+## Configuring Munin
+
+Simply add `munin_node_name` surrounded by brackets to `/etc/munin/munin.conf`:
+
+``` ini
+[xmpp.example.com]
+address = xmpp.example.com
+port = 4949
+```
+
+You can leave out `address` if it equal to the name in brackets, and
+leave out the `port` if it is the default (`4949`).
+
+Setting `address` to an IP address may sometimes be useful as the Munin
+collection server is not delayed by DNS lookups in case of network
+issues.
+
+If you set a different port, or if the hostname to connect to is
+different from this hostname, make sure to add `port` and/or `address`
+options.
+
+See [Munin documentation][muninconf] for more information.
