 # freenas-iocage-caddy
-Script to install Caddy V2 in a FreeNAS jail
+The aim is to develop a script to install Caddy V2 in a FreeNAS jail
 
-## 
+### Currently supported
+
+The centrepiece is a rc.d script, which supports default methods such as `service caddy stop` and `service caddy status`, but also includes a modifed `service caddy start` method to support the Caddy V2 executable as well as the following extra commands:
+
+service caddy reload - A config reload with zero downtime. More info at https://caddyserver.com/docs/command-line#caddy-reload
+service caddy validate - Check for a valid Caddyfile configuration. More info at https://caddyserver.com/docs/command-line#caddy-validate
+
+Additional commands may be added at a later stage if deemed useful. 
+
+For other configurable script parameters, refer to the comments at the top of the rc.d script. At this stage, configurable script parameters include:
+
+caddy_enable - Set to enable caddy. The default is disabled.
+caddy_bin_path - location of the Caddy executable. The default is /usr/local/bin/caddy.
+caddy_config_path - location of the Caddyfile. The default is /usr/local/www/Caddyfile
+
+To change the defaults add lines to /etc/rc.conf. For example:
+sysrc caddy_enable="YES"
+sysrc caddy_bin_path="/usr/local/sbin/caddy"
+
+Additional configrable script parameters may be added at a later stage if deemed useful. 
 
 ### To Do
 
 #### Build the install script
+
+The script will mirror the steps below, that are presently manually executed.
  ```
 # Set up the jail
  iocage create --name="caddyv2" -r 11.3-RELEASE ip4_addr="vnet0|10.1.1.45/24" defaultrouter="10.1.1.1" boot="on" host_hostname="caddyv2" vnet="on"
