 ## Certbot
 
-This module can optionally setup [certbot](https://certbot.eff.org/) TLS certificate management for the frontend GUI. In order to do so, set `$ng_enable_certbot`  as well as `$ng_use_https` 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. Certs are also automatically renewed.

 If you prefer to use https but use self-signed certs or your own CA, simply set to false. This will point the SSL vhost config file to the default location for TLS certificates.
 
 ## 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 for performance reasons), we will not want to manage ssl.conf directly, hence the module creates a vhost for the ssl host.
