-- SBCL,
-- Quicklisp,

+## For macOS
 
-You only need to download Portacle and double-click to run it.
+Use [homebrew](https://brew.sh) to install Emacs, git and SBCL:
+
+```shell
+brew tap d12frosted/emacs-plus

+
+### Quicklisp
+
+To download Quicklisp:
+
+```shell
+curl -O https://beta.quicklisp.org/quicklisp.lisp
+```
+Start SBCL REPL and install Quicklisp:
+
+```shell
+$ sbcl --load quicklisp.lisp
+```
+at the REPL prompt `*` enter:

+```lisp
+(ql:add-to-init-file)
+```
+
+Exit SBCL:

+```
+
+### Configure packages for Emacs
+
+Start Emacs and the [first buffer](https://www.gnu.org/software/emacs/manual/html_node/emacs/Lisp-Interaction.html) you see is going to be called `*scratch*`. In it enter the following:
+
+```emacs-lisp
+(progn
+  (require 'package)
+
+  ;; Add MELPA repository if not already present
+  (unless (assoc "melpa" package-archives)
+    (add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t))
+
+  ;; Initialize package system
+  (package-initialize)
+
+  ;; Refresh package contents if needed
+  (unless package-archive-contents
+    (package-refresh-contents))
+
+  ;; Install SLIME if not already installed
+  (unless (package-installed-p 'slime)
+    (package-install 'slime)
+    (message "SLIME installed successfully!"))
+
+  ;; Basic SLIME configuration
+  (setq inferior-lisp-program "sbcl")  ; Change to your Lisp implementation
+  (setq slime-contribs '(slime-fancy))
+
+  (message "SLIME setup complete! Use M-x slime to start."))
+```
+
+Move your cursor to the end of the last parenthesis and type `C-x
+C-e`. That is press the `Control` key and hold it and press `x`, then
+while still holding down `Control` key, press `e`, followed by
+`Enter`.
