+About a month ago I was a little bored and thought I'd give emacs a go. There's something fun about trying out these mythical pieces of software that have been around forever; kind of like watching The Godfather for the first time. Like many extensible, super configurable programs, emacs seems kind of impenetrable at first glance. I tried doing the tutorial but kind of glazed over after a while with the endless stream of C-a C-b C-c. There's also the quite jarring default theme which wasn't vibing with the lovely screenshots I had seen on the internet. Anyway, after quite a bit of fiddling I've landed on a simple little setup that I've been quite enjoying. Here are a few little pointers to hopefully ease you in.
+
+### AESTHETIC NICETIES
+
+First things first, assuming you're on linux emacs is configured with a file at `~/.emacs.d/init.el`. As a terrible aesthete, the first thing I was worried about was changing the theme. This can be achieved with `M-x load-theme`; if you want the setting to persist though you can add this to you init.el:
+
+```lisp
+(load-theme 'misterioso t)
+```
+
+There are a few themes out of the box but if you're looking for some more I would recomment the doom-themes package. Speaking of packages, emacs has a built in package-manager that installs packages from the Emacs Lisp Package Archive (GNU ELPA); I unfortunately know very little about this as I've been using nix to manage my emacs packages.
+
+Anyway we've got a theme, how about a custom startup message for our initial buffer:
+
+```lisp
+(setq inhibit-startup-message t
+      inhibit-startup-echo-area-message t
+      initial-scratch-message
+      ";;oh how i adore to edit text with emacs!")
+```
+
+Maybe you dont want those big old cumbersome toolbars cluttering up your screen:
+
+```lisp
+(scroll-bar-mode -1)
+(tool-bar-mode -1)
+(menu-bar-mode -1)
+```
+
+Perhaps some line highlighting and numbering:
+
+```lisp
+;;line numbering
+(global-display-line-numbers-mode)
+(setq display-line-numbers-type 'relative)
+
+;;line higlight
+(global-hl-line-mode t)
+```
+
+Custom font?
+
+```lisp
+(setq default-frame-alist '((font . "agave Nerd Font 14")))
+```
+
+### CUSTOM KEYBINDINGS AND EVIL
+I don't know if it's just sunk cost fallacy or what but having gone to the trouble of learning to some extent how vim works, I kind of feel incomplete without vim keybindings now. Fortunately, emacs has evil mode which effectively emulates vim modal editing in emacs. To configure evil in our init.el we'll use use-package. This is a macro which - to my understanding - talks to your package manager allowing you to configure installed packages in a nice neat efficient manner. To enable it, add this to your init.el:
+
+```lisp
+(eval-when-compile
+  (require 'use-package))
+```
+
+These are the keybindings that I currently have going; nothing too crazy just a few simple things:
+
+```lisp
+(use-package evil
+  :config
+  (evil-mode 1)
+  (evil-select-search-module 'evil-search-module 'evil-search)
+
+  ;;manage panes
+  (define-key evil-normal-state-map (kbd "M-s") 'evil-window-split)
+  (define-key evil-normal-state-map (kbd "M-v") 'evil-window-vsplit)
+
+  (define-key evil-normal-state-map (kbd "M-h") 'evil-window-left)
+  (define-key evil-normal-state-map (kbd "M-j") 'evil-window-down)
+  (define-key evil-normal-state-map (kbd "M-k") 'evil-window-up)
+  (define-key evil-normal-state-map (kbd "M-l") 'evil-window-right)
+
+  ;;get files open quick
+  (define-key evil-normal-state-map (kbd "M-f") 'find-file)
+  (define-key evil-normal-state-map (kbd "M-b") 'dired-jump)
+  
+  ;;terminal
+  (define-key evil-normal-state-map (kbd "M-t") 'ansi-term)
+  
+  ;;nav buffers
+  (define-key evil-normal-state-map (kbd "M-,") (kbd "C-x <left>"))
+  (define-key evil-normal-state-map (kbd "M-.") (kbd "C-x <right>"))
+  )
+```
+
+### SOME FRIEDNLY IDE FEATURES YOU MAY LIKE
+
+ I don't know about you but having used vscode here and there I've become accustomed to a lot of these little IDE crutches (completion, autopair and the like) and now when I don't have thme I feel a little sad. Emacs has it covered though as long as you're happy with installing some additional stuff. Auto-completion? Try company:
+
+```lisp
+;; enable company in all buffers
+(add-hook 'after-init-hook 'global-company-mode)
+(use-package company			
+  :commands company-tng-configure-default
+  :custom
+  ;; delay to start completion
+  (company-idle-delay 0)
+  ;; nb of chars before triggering completion
+  (company-minimum-prefix-length 1)
+```
+
+You want the nice little autopair brackets?
+
+```lisp
+(use-package flex-autopair
+  :config
+  (flex-autopair-mode 1))
+```
+
+Clever commenting?
+
+```lisp
+(use-package smart-comment
+  :bind ("M-c" . smart-comment))
+```
+
+Here's a little pic of the current setup :)
