 ## Intro
 
 A Prometheus exporter for [WireGuard](https://www.wireguard.com), written in Rust. This tool exports the `wg show all dump` results in a format that [Prometheus](https://prometheus.io/) can understand. The exporter is very light on your server resources, both in terms of memory and CPU usage.

 ## Prerequisites 
 
@@ -43,9 +43,102 @@ Start the binary with `-h` to get the complete syntax. The parameters are:
 | -- | -- | -- | -- | -- | 
 | `-v` | no | <switch> | | Enable verbose mode.
 | `-p` | no | any valid port number | 9576 | Specify the service port. This is the port your Prometheus instance should point to.
+| `-n` | no | path to the wireguard configuration file | | This flag adds the *friendly_name* attribute to the exported entries. See [Friendly names](#friendly-names) for more details.
 
 Once started, the tool will listen on the specified port (or the default one, 9576, if not specified) and return a Prometheus valid response at the url `/metrics`. So to check if the tool is working properly simply browse the `http://localhost:9576/metrics` (or whichever port you choose).
 
+## Friendly Names
+
+Starting from version 1.2 you can instruct the exporter to append a *friendly name* to the exported entries. This can make the output more understandable than using the public keys. For example this is the standard output:

+
+In order for this to work, you need to add comments to your wireguard configuration file (below the `[Peer]` definition). The comment will be interpreted as `friendly_name` and added to the entry exported to Prometheus. Note that this is not a standard but, since it's a comment, will not interfere with WireGuard in any way. For example this is how you edit your WireGuard configuration file:
+
+```
+[Peer]
+PublicKey = lqYcojJMsIZXMUw1heAFbQHBoKjCEaeo7M1WXDh/KWc=
+AllowedIPs = 10.70.0.40/32
+
+[Peer]
+PublicKey = 928vO9Lf4+Mo84cWu4k1oRyzf0AR7FTGoPKHGoTMSHk=
+AllowedIPs = 10.70.0.80/32
+```
+
+```
+[Peer]
+# frcognowin10
+PublicKey = lqYcojJMsIZXMUw1heAFbQHBoKjCEaeo7M1WXDh/KWc=
+AllowedIPs = 10.70.0.40/32
+
+[Peer]
+# OnePlus 5T
+PublicKey = 928vO9Lf4+Mo84cWu4k1oRyzf0AR7FTGoPKHGoTMSHk=
+AllowedIPs = 10.70.0.80/32
+```
+
+As you can see, all you need to do is to add the friendly name as comment (and enable the flag since this feature is opt-in).
+
 ### Systemd service file
 
 Now add the exporter to the Prometheus exporters as usual. I recommend to start it as a service. It's necessary to run it as root (if there is a non-root way to call `wg show all dump` please let me know). My systemd service file is like this one:
