 ### SELINUX
 All files and directories are configured with correct selinux context. If selinux is disabled, these contexts are ignored.
 
+### Certbot
+This module can optionally setup [certbot](https://certbot.eff.org/) TLS certificate management for the frontend GUI. In order to do so, set `ng_enable_certbot` to true (default).  Effectively, this will manage the certs before even installing Nagios, so there will be no problems with the Nagios showing up with a self-signed certificate.
+Once enabled, the module will go and try to obtain a certificate automatically. For this to work, you need to have proper DNS resolution set up for your domain / nagios server.
+
+### httpd vHost files
+by Default, Nagios creates its own nagios.conf file, which is not a vhost file and relies on the main ssd.conf. However, as Nagios might be running on a regular web server with various other web instances (not recommended through), we will not want to manage ssl.conf directly, hence the module creates a vhost for the ssl host.
