Although later versions of Emacs introduce =early-init.el=, it's not used in this configuration for two reasons:
+ It's not required due to the modularity
+ Maintaining support for older versions
Assuming you have completed all of the following tasks prior to proceeding further:
1. Imported the =secrets=
2. Initialized the =passwords=
3. Defined the =host= file
4. Created all required symbolic links
Launch emacs: ~emacs -mm --debug-init~
This section controls initialization of the system, everything is available from a top-down perspective at this stage in the configuration.
**Options
** Hosts
Here's a complete list of all of the options configurable for each host, and their default values. Override any of these configurations in a host file. All of the values are prefixed with ~dotfiles/~. If you need to make configurations to another variable, consider creating a new option. Here are a few examples to get started:

+ [[file:hosts/raspberry.org][Raspberry]]
+ [[file:hosts/acernitro.org][Acernitro]]

This section contains configuration for improving the editor experience within Emacs.
*** Keys
Make the =ESC= key quit (most) prompts, instead of the default =C-g=.
Download [[https://github.com/justbur/emacs-which-key][which-key]], a package that displays the current incomplete keybinding input in a mini-buffer, showing available completion options.
#+begin_src emacs-lisp
(use-package which-key
:diminish which-key-mode
:custom (which-key-idle-delay dotfiles/idle)
:config (which-key-mode))
#+end_src
Turn Emacs into Vim with [[https://evil.readthedocs.io/en/latest/index.html][evil-mode]], the extensible VI layer for Emacs.
#+begin_src emacs-lisp
(use-package evil
:custom (evil-want-integration t) ;; Required for `evil-collection'.
(evil-want-keybinding nil) ;; Same as above
:config (evil-mode 1))
#+end_src
Unfortunately the default keybindings are *lacking*, but there is a community curated package [[https://github.com/emacs-evil/evil-collection][evil-collection]], which does a much better job implementing keybindings you would expect to find.
#+begin_src emacs-lisp
(use-package evil-collection
:after evil
:config (evil-collection-init))
#+end_src
Surround text with functions, quotations, and any other symbols using the [[https://github.com/emacs-evil/evil-surround][evil-surround]] package.
#+begin_src emacs-lisp
(use-package evil-surround
:after evil
:config (global-evil-surround-mode 1))
#+end_src
Toggle block comments using [[https://github.com/redguardtoo/evil-nerd-commenter][evil-nerd-commentor]] and =M-;=.
Implement the *leader* key using [[https://github.com/noctuid/general.el][general.el]], letting us easily configure prefixed keybindings in a much cleaner manner than the default methods.
#+begin_src emacs-lisp
(use-package general
:after evil
:config
(general-create-definer dotfiles/leader
:states '(normal motion)
:keymaps 'override
:prefix dotfiles/leader-key
:global-prefix dotfiles/leader-key-global))
#+end_src
Use [[https://github.com/abo-abo/hydra][hydra]] for transient keybindings sharing a common prefix.
#+begin_src emacs-lisp
(use-package hydra
:defer t)
#+end_src
*** Help
Use the built-in ~describe-*~ functionality of Emacs to quickly access documentation for packages, variables, and functions. Run helper functions with =SPC h=.
+ Packages =p=
+ Variables =v=
+ Functions =f=
#+begin_src emacs-lisp
(dotfiles/leader
"h" '(:ignore t :which-key "Help")
"hp" '(describe-package :which-key "Package")
"hv" '(describe-variable :which-key "Variable")
"hf" '(describe-function :which-key "Function"))
#+end_src
*** Files
For file navigation I use =dired=, included with Emacs by default. Dired feels more modern with prioritized icon fonts using [[https://github.com/domtronn/all-the-icons.el][all-the-icons]]. This makes navigation and visually parsing directories much faster, given that file types are quickly identified by their corresponding icons.
#+begin_src emacs-lisp
(use-package all-the-icons)
#+end_src
Integration with =dired= comes from the [[https://github.com/jtbm37/all-the-icons-dired][all-the-icons-dired]] package.
#+begin_src emacs-lisp
(use-package all-the-icons-dired
:hook (dired-mode . all-the-icons-dired-mode))
#+end_src
When opening =dired=, I don't want to have to press =RET= twice to navigate to the current directory. Avoid this with ~dired-jump~, included in the =dired-x= package shipped with =dired= and Emacs.
#+begin_src emacs-lisp
(require 'dired-x)
#+end_src
By default =dired= will create a new buffer everytime you press =RET= over a directory. This leads to unwanted =dired= buffers needing closure. Avoid this behaviour with [[https://github.com/crocket/dired-single][dired-single]], reusing the same dired buffer.
While not a traditional terminal emulator, =eshell= provides me with all of the functionality I expect and require from one. Some users may be wanting more, I would recommend they look into =vterm= included in the destkop module. Configure the infamous lambda prompt using [[https://github.com/zwild/eshell-prompt-extras][eshell-prompt-extras]] package.
#+begin_src emacs-lisp
(use-package eshell-prompt-extras
:custom (eshell-highlight-prompt nil)
(eshell-prefer-lisp-functions nil)
(eshell-prompt-function 'epe-theme-lambda))
#+end_src
Open an =eshell= buffer with =SPC e=.
#+begin_src emacs-lisp
(dotfiles/leader
"e" '(eshell :which-key "Shell"))
#+end_src
