-Package nut implements the Network UPS Tools network protocol.
+# uni-nut
+This is a subset of [go-nut](https://github.com/dominikh/go-nut) meant specifically for connecting to and monitoring variables on Ubiquiti UniFi UPS NUT servers.
 
-This package only implements those functions necessary for the
-nut_exporter; it is therefore not complete.
+Ubiquiti UPS units seem to use a somewhat non-standard format for responses from the in-built NUT server. Because of this, many existing NUT clients (including the module this project was forked off of) fail to function with Ubiquiti UPS units.
+
+## Usage
+1. Enable the NUT server on your Ubiquiti UniFi-connected UPS unit.
+    - Do **NOT** enable the "Login Credential" option!
+2. This module can now be used to get variables from your UPS's NUT server as follows:
+```go
+package main
+
+import (
+	"fmt"
+
+	nut "github.com/rwinkhart/uni-nut"
+)
+
+func main() {
+	host := "IP:PORT"
+	upsID := "UPS-ID"
+	client, err := nut.Dial(host)
+	if err != nil {
+		panic(err)
+	}
+	err = client.GetListVar(upsID)
+	if err != nil {
+		panic(err)
+	}
+	for key, value := range nut.NutKeyValMap {
+		fmt.Println(key + ": " + value)
+	}
+}
+```
