Plone 5.0.8 and LDAP

Hi,
I am looking for some help on installing ldap with Plone 5.0.8. I have very little experience with Plone as I just loaded it up a couple of weeks ago following the Plone documentation basically word for word. I'm not very familiar with Linux either, but I got the site up and running. If someone could give me a step by step instruction on how to get pas.plugin.ldap installed I would really appreciate it. I've looked at some postings on this, but I haven't been able to figure it out.
