+Linux Manual Installation
+-------------------------
+
+With most desktop-oriented distributions, double-clicking each font file in the ttf folder and selecting “Install font” should be enough. If it isn’t, create and run `download_and_install.sh` script:
+
+    #!/usr/bin/env bash
+
+    fonts_dir="${HOME}/.local/share/fonts"
+    if [ ! -d "${fonts_dir}" ]; then
+        echo "mkdir -p $fonts_dir"
+        mkdir -p "${fonts_dir}"
+    else
+        echo "Found fonts dir $fonts_dir"
+    fi
+
+    for type in Bold Light Medium Regular Retina; do
+        file_path="${HOME}/.local/share/fonts/FiraCode-${type}.ttf"
+        file_url="https://github.com/tonsky/FiraCode/blob/master/distr/ttf/FiraCode-${type}.ttf?raw=true"
+        if [ ! -e "${file_path}" ]; then
+            echo "wget -O $file_path $file_url"
+            wget -O "${file_path}" "${file_url}"
+        else
+      echo "Found existing file $file_path"
+        fi;
+    done
+
+    echo "fc-cache -f"
+    fc-cache -f

+
+    pkg install firacode
+
+OR
+
+Using ports:
+
+    cd /usr/ports/x11-fonts/firacode && make install clean
+
+
+Enabling ligatures
+==================
+
+Atom
+----
+
+To change your font to Fira Code, open Atom's preferences (`cmd + ,` on a Mac, `ctrl + ,` on PC), make sure the "Settings" tab is selected, or the "Editor" in Atom 1.10+, and scroll down to "Editor Settings". In the "Font Family" field, enter `Fira Code`.
+
+If you wish to specify a font weight, for example, Light, use `Fira Code Light` as a font name (Windows) or `FiraCode-Light` (macOS).
+
+Ligatures are enabled by default in Atom 1.9 and above.
+
+
+VS Code
+-------
+
+To open the settings editor, first from the File menu choose Preferences, Settings or use keyboard shortcut `Ctrl + ,` (Windows) or `Cmd + ,` (macOS).
+
+To enable FiraCode in the settings editor, under "Commonly Used", expand the "Text Editor" settings and then click on "Font". In the "Font Family" input box type `Fira Code`, replacing any content. Tick the check box "Enables/Disables font ligatures" under "Font Ligatures" to enable the special ligatures.
+
+If you wish to specify a font weight, for example, Light, use `Fira Code Light` as a font name (Windows) or `FiraCode-Light` (macOS).
+
+
+IntelliJ products
+-----------------
+
+1. Enable in Settings → Editor → Font → Enable Font Ligatures
+2. Select `Fira Code` as "Primary font" under Settings → Editor → Font
+
+Additionally, if a Color Scheme is selected:
+
+3. Enable in Settings → Editor → Color Scheme → Color Scheme Font → Enable Font Ligatures
+4. Select Fira Code as "Primary font" under Settings → Editor → Color Scheme → Color Scheme Font
+
+
+BBEdit, TextWrangler

+
+    defaults write com.barebones.bbedit "EnableFontLigatures_Fira Code" -bool YES
+
+Source: https://www.barebones.com/support/bbedit/ExpertPreferences.html
+
+
+Brackets
+--------
+
+1. From the `View` menu choose `Themes....`
+2. Paste `'Fira Code'`, at the beginning of `Font Family`
+
+
+Emacs
+-----
+
+There are a few options when it comes down to using ligatures in
+Emacs. They are listed in order of preferred to less-preferred. Pick one!
+
+1. Using composition mode in Emacs Mac port
+
+If you're using the latest Mac port of Emacs (https://bitbucket.org/mituharu/emacs-mac by Mitsuharu Yamamoto) for macOS, you can use:
+
+    (mac-auto-operator-composition-mode)
+
+This is generally the easiest solution, but can only be used on macOS.
+
+2. Using prettify-symbols
+
+These instructions are pieced together by https://github.com/Triavanicus, taking some pieces from https://github.com/minad/hasklig-mode.
+
+This method requires you to install the Fira Code Symbol font, made by https://github.com/siegebell:
+https://github.com/tonsky/FiraCode/issues/211#issuecomment-239058632
+
+    (defun fira-code-mode--make-alist (list)

+           (let* ((code (+ #Xe100 idx))
+              (width (string-width s))
+              (prefix ())
+              (suffix '(?\s (Br . Br)))
+              (n 1))
+         (while (< n width)
+           (setq prefix (append prefix '(?\s (Br . Bl))))
+           (setq n (1+ n)))
+         (cons s (append prefix suffix (list (decode-char 'ucs code))))))

+
+3. Using composition char table
+
+Thanks to https://github.com/seanfarley for putting this together; extended by https://github.com/jrblevin.
+
+Put this lisp in your .emacs:
+
+    (when (window-system)
+      (set-frame-font "Fira Code"))
+    (let ((alist '((33 . ".\\(?:\\(?:==\\|!!\\)\\|[!=]\\)")
+                   (35 . ".\\(?:###\\|##\\|_(\\|[#(?[_{]\\)")
+                   (36 . ".\\(?:>\\)")
+                   (37 . ".\\(?:\\(?:%%\\)\\|%\\)")
+                   (38 . ".\\(?:\\(?:&&\\)\\|&\\)")
+                   (42 . ".\\(?:\\(?:\\*\\*/\\)\\|\\(?:\\*[*/]\\)\\|[*/>]\\)")
+                   (43 . ".\\(?:\\(?:\\+\\+\\)\\|[+>]\\)")
+                   (45 . ".\\(?:\\(?:-[>-]\\|<<\\|>>\\)\\|[<>}~-]\\)")
+                   (46 . ".\\(?:\\(?:\\.[.<]\\)\\|[.=-]\\)")
+                   (47 . ".\\(?:\\(?:\\*\\*\\|//\\|==\\)\\|[*/=>]\\)")
+                   (48 . ".\\(?:x[a-zA-Z]\\)")
+                   (58 . ".\\(?:::\\|[:=]\\)")
+                   (59 . ".\\(?:;;\\|;\\)")
+                   (60 . ".\\(?:\\(?:!--\\)\\|\\(?:~~\\|->\\|\\$>\\|\\*>\\|\\+>\\|--\\|<[<=-]\\|=[<=>]\\||>\\)\\|[*$+~/<=>|-]\\)")
+                   (61 . ".\\(?:\\(?:/=\\|:=\\|<<\\|=[=>]\\|>>\\)\\|[<=>~]\\)")
+                   (62 . ".\\(?:\\(?:=>\\|>[=>-]\\)\\|[=>-]\\)")
+                   (63 . ".\\(?:\\(\\?\\?\\)\\|[:=?]\\)")
+                   (91 . ".\\(?:]\\)")
+                   (92 . ".\\(?:\\(?:\\\\\\\\\\)\\|\\\\\\)")
+                   (94 . ".\\(?:=\\)")
+                   (119 . ".\\(?:ww\\)")
+                   (123 . ".\\(?:-\\)")
+                   (124 . ".\\(?:\\(?:|[=|]\\)\\|[=>|]\\)")
+                   (126 . ".\\(?:~>\\|~~\\|[>=@~-]\\)")
+                   )
+                 ))
+      (dolist (char-regexp alist)
+        (set-char-table-range composition-function-table (car char-regexp)
+                              `([,(cdr char-regexp) 0 font-shape-gstring]))))
+
+**Note!** If you get `error in process filter: Attempt to shape unibyte text`, check out https://github.com/tonsky/FiraCode/issues/42. Emacs Cider users may avoid this issue by commenting the following line from the above config:
+
+    ;; (46 . ".\\(?:\\(?:\\.[.<]\\)\\|[.=-]\\)")
+
+Char `45` is also known to have issues in macOS Mojave.
+
+If you are having problems with helm you can disable ligatures in helm:
+
+    (add-hook 'helm-major-mode-hook
+           (lambda ()
+             (setq auto-composition-mode nil)))
+
+4. Using font-lock keywords
+
+If none of the above worked, you can try this method.
+
+This method requires you to install the Fira Code Symbol font, made by https://github.com/siegebell:
+https://github.com/tonsky/FiraCode/issues/211#issuecomment-239058632
+
+    ;;; Fira code
+    ;; This works when using emacs --daemon + emacsclient
+    (add-hook 'after-make-frame-functions (lambda (frame) (set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol")))
+    ;; This works when using emacs without server/client
+    (set-fontset-font t '(#Xe100 . #Xe16f) "Fira Code Symbol")
+    ;; I haven't found one statement that makes both of the above situations work, so I use both for now
+
+    (defconst fira-code-font-lock-keywords-alist
+      (mapcar (lambda (regex-char-pair)
+                `(,(car regex-char-pair)
+                  (0 (prog1 ()
+                       (compose-region (match-beginning 1)
+                                       (match-end 1)
+                                       ;; The first argument to concat is a string containing a literal tab
+                                       ,(concat "   " (list (decode-char 'ucs (cadr regex-char-pair)))))))))
+              '(("\\(www\\)"                   #Xe100)
+                ("[^/]\\(\\*\\*\\)[^/]"        #Xe101)

+3. Hit "OK" and enjoy
+
+
+Sublime Text
+------------
+
+Preferences --> Settings
+
+Add before "ignored_packages":
+
+    "font_face": "Fira Code",
+    "font_options": ["subpixel_antialias"],
+
+If you want enable antialias, add in font_options: "gray_antialias"
+
+
+Visual Studio
+-------------
+
+1. Launch Visual Studio (2015 or later).
+2. Launch the Options dialog by opening the "Tools" menu and selecting "Options". 
+3. In the Options dialog, under the "Environment" category, you'll find "Fonts and Colors". Click on that. You'll see a combo-box on the right hand side of the dialog labelled "Font". Select "Fira Code" from that combo-box.
