+### Option: `mode`
+
+The `mode` option configures chrony to use either `pool` or `server` mode.
+These options are:
+
+- `pool`: References a pool of servers such as pool.ntp.org (Recommended).
+- `server`: References a list of specific names or addresses.
+  
+Based on the mode the `ntp_pool` or `ntp_server` option will be used.
+
+### Option: `ntp_pool`
+
+Used by pool mode and configures the pool name to be used, should be a DNS
+record with multiple entries. The application will select which to reference.
+
+### Option: `ntp_server`
+
+Used by server mode, an array of server names or IP Addresses used as the
+time source. The application will select which to reference.

 ## Known issues and limitations
 
 - This does not control the local system time and is purely an NTP server.
