#+TITLE: Emacs Configuration from [[https://gitlab.com/TuDatTr/][TuDatTr]]
#+SETUPFILE: ~/Templates/Org-Mode/setupfile.org
#+OPTIONS: \n:t
* Preface
Before installing and using emacs, emacs should be run as a daemon.
This decreases the loading times of the editor enormously and enables you to return to your former emacs session at any time.
To do this you first need to make sure ~emace --daemon~ is run during the start up.
To access the daemonized emacs you can either run ~emacsclient -t~ to use it in the terminal or simply ~emacsclient~ if you want to use the GUI version.
* Package installation
** Preperation
Initialize Emacs builtin package system and add the [[https://melpa.org][melpa]]-package repository.
