IRC client IRSSI setup

I use IRC on remote server more and more frequently, in case I need to config this in the future, the regarding setup steps are consolidated here.

Install
$ sudo apt install irssi

Start by:
screen irssi

Hilight Window
Put the script in ~/.irssi/scripts/autorun/ and type /run autorun/hilightwin.pl in irssi.
then create the split window.

/window new split
/window name hilight
/window size 6

Setup the proxy
/server list
See if your IRC server is on the list. If so, write down the short network name that you see next to the DNS name.
/server add -auto [netname] [server] [server-port]
You can do a /server list again if you want to verify that your server is on the list now.

/load proxy
/set irssiproxy_password [password]
/set irssiproxy_ports Canonical=6697

If you get the error: Irssi: Unknown command: SCRIPT
/load perl

Connect a IRC client to irssi-proxy
Each IRC client is a little different, but the gist of it is this: Connect to your irssi-proxy IP address (or DNS name), at the irssi-proxy port, with the password. The client should connect, give you the same name as the irssi-proxy, and load all the channels that your irssi-proxy has, automatically.
The command to connect irssi to the irssi-proxy client is here (do not do this from the irssi-proxy server):

/server [irssi-proxy-ip-or-name] [proxy-port] [password]
