+            description: |
+              The plugin is disabled by default because the number of PMUs is usually quite limited and it is not desired to allow Netdata to struggle silently for PMUs, interfering with other performance monitoring software.
+
+              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 `netdata.conf` file.
+
+              ```bash
+              cd /etc/netdata   # Replace this path with your Netdata config directory, if different
+              sudo ./edit-config netdata.conf
+              ```
+
+              Change the value of the `perf` setting to `yes` in the `[plugins]` section. 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.
