Set up external sasl authentication for the irc server you will be connecting to. Here's how to do
it on freenode: https://freenode.net/kb/answer/certfp

Edit /etc/matrix-appservice-irc/config.yaml :
  - saslType to EXTERNAL
  - sasl to true
  - ssl to true
  - key and cert to the ones you set up in the previous step

It's recommended to install matrix-appservice-irc-runit if you use runit which will
install a service that automatically initializes the bridge and starts it.

If you can't use the runit package, here's how to set up the bridge yourself:

Run this once to generate your registration file

  sudo node /usr/lib/node_modules/matrix-appservice-irc/app.js \\
    --config /etc/matrix-appservice-irc/config.yaml \\
    --file /etc/matrix-appservice-irc/registration.yaml \\
    --generate-registration --url 'http://localhost:9999' \\
    --localpart irc_bot

Edit your homeserver config and add the registration.yaml, for synapse it would be:

  app_service_config_files:
      - /etc/matrix-appservice-irc/registration.yaml

Now you can start the bridge:

  sudo node /usr/lib/node_modules/matrix-appservice-irc/app.js \\
    --config /etc/matrix-appservice-irc/config.yaml \\
    --file /etc/matrix-appservice-irc/registration.yaml
"
