Emacs package management
From wikinotes
Emacs ships with a package/plugin manager.
Usage
Provided that you have the package-archives variable (defined below) set up, you can search/download from the package-archives using:
<M-x> package-list ;; show all packages <M-x> package-refresh-contents ;; refresh package index <C-s> <package-you-are-looking-for> ;; install package
Configuration

"https://elpa.gnu.org/packages/"))) (require 'package) (package-initialize) (unless package-archive-contents (package-refresh-contents)) (unless (package-installed-p 'use-package) (package-install 'use-package)) (require 'use-package) (setq use-package-always-ensure t)Adding Packages

(use-package neotree :ensure t)If you're having issues downloading a package, try
