Nfsen and freenms integration

Hello, could someone give me a link where the installation and integration of nfsen and librenms is explained step by step? I searched and I tried and I couldn’t, thank you very much.

check here ->

I have not been able to reach that step because I have not been able to install the nfsen, it gives me an error, do you have a link that you have used for the installation of nfsen that you can share with me?
