+#### Temperature
+
+This widget shows hardware temperature sensor data as a bar graph.
+
+```toml
+[keys.widget]
+  id = "temp"
+  [keys.widget.config]
+    sensorKey = "k10temp_tctl"
+    label = "CPU"
+    maxTemp = 100 #optional
+    color = "#fefefe" # optional
+    fillColor = "#d497de" # optional
+```
+
+The values for sensorKey are platform dependent. On most Linux systems they're
+based on the [hwmon-sysfs-interface](https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface) under `/sys/class/hwmon`.
+
+Example: `k10temp_tctl`
+
+- `k10temp`: the name for a specific sensor interface, for example, the value
+reported from `/sys/class/hwmon/hwmon0/name`
+- `tctl`: the label for a specific sensor, for example, the value reported from
+`/sys/class/hwmon/hwmon0/temp1_label` (label is converted to lowercase and
+spaces are replaced with underscores)
+- For this example, the temperature value would be available in `/sys/class/hwmon/hwmon0/temp1_input`
+
+For the full explanation on how these sensor keys are created on all platforms,
+check the `SensorTemperatures*` functions in the [gopsutil](https://github.com/shirou/gopsutil/blob/master/host/host.go)
+package.
