ERC is an Internet Relay Chat (IRC) client built into Emacs.

Basic setup

Start ERC using M-x erc to connect without SSL or M-x erc-tls to connect with SSL.

Helpful keybindings

Common customization

(eval-after-load "erc"

     ;; Set personal information
     (setq erc-nick "defaultnick")
     (setq erc-user-full-name "My Full Name")

     ;; Set autojoin channels
     (setq erc-autojoin-channels-alist
           '(("" "#emacs" "#foo" "#bar")))))

;; Set autoconnect networks
(defun my-erc ()
  "Connect to my default ERC servers."

  (erc-tls :server "" :port 7000))

Using the above configuration, M-x my-erc will start ERC and connect to Freenode on port 7000 using SSL, then join #emacs, #foo and #bar.
