* Initial setup

These commands need to be run after the first startup.

** Irony mode

M-x =irony-install-server=

** All the icons

M-x =all-the-icons-install-fonts=

* Customizations

Store custom-file separately, don't freak out when it's not found.

#+BEGIN_SRC emacs-lisp
  (setq custom-file (concat emacs-d "/custom.el"))
  (load custom-file 'noerror)
#+END_SRC

Set custom faces, without using customize.

#+BEGIN_SRC emacs-lisp
  (set-face-attribute 'default nil :height 90 :family "DejaVu Sans Mono")
#+END_SRC

* Package Management
** Ensure

Ensures packages are installed by default.

#+BEGIN_SRC emacs-lisp
  (require 'use-package-ensure)
  (setq use-package-always-ensure t)
#+END_SRC

** Auto update

Update pending updates of installed packages at startup.
https://github.com/rranelli/auto-package-update.el
