 To gather data from remote systems you can use LibreNMS in combination with check_mk (included in the scripts directory).
 
+Make sure that xinetd is installed on the host you want to run the agent on.

 The agent uses TCP-Port 6556, please allow access from the LibreNMS-Host and Poller-Nodes if you're using the Distributed Polling setup.
 
 On each of the hosts you would like to use the agent on then you need to do the following:
 
-* Copy the `check_mk_agent` script into `/usr/bin` and make it executable.
+* Clone the `librenms-agent` repository:
 
 ```shell
-cp scripts/check_mk_agent /usr/bin/check_mk_agent
+cd /opt/
+git clone https://github.com/librenms/librenms-agent.git
+cp check_mk_agent /usr/bin/check_mk_agent
 chmod +x /usr/bin/check_mk_agent
 ```
 
 * Copy the xinetd config file into place.
 
 ```shell
-cp scripts/check_mk_xinetd /etc/xinetd.d/check_mk
+cp check_mk_xinetd /etc/xinetd.d/check_mk
 ```
