+            description: |
+              The `sensors` collector is disabled by default. To enable it, use `edit-config` from the Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md), which is typically at `/etc/netdata`, to edit the `charts.d.conf` file.
+
+              ```bash
+              cd /etc/netdata   # Replace this path with your Netdata config directory, if different
+              sudo ./edit-config charts.d.conf
+              ```
+
+              Change the value of the `sensors` setting to `force` and uncomment the line. Save the file and restart the Netdata Agent with `sudo systemctl restart netdata`, or the [appropriate method](https://github.com/netdata/netdata/blob/master/docs/configure/start-stop-restart.md) for your system.
