+
+* Installing Debian
+** Preparations
+*** Getting debian
+Download Debian [[https://www.debian.org/][installer image]]
+
+*** Creating installation medium
+On =M$= Windows, use a tool like [[https://rufus.ie/en/][Rufus]] to create a bootable USB flash
+drive with the downloaded =.iso= file
+
+*** Allocating disk space
+Either get an empty disk or shrink on of your data partitions (toms) to get a continuous region of free space which is at least around 100GB.
+
+** Installation process
+If installing on a laptop, make sure that it's fully charged and keep
+the charger plugged in.
+
+*** Booting from the installation medium
+NOTE: You might have to enable booting from USB in BIOS.
+
+Select the USB from boot menu or change boot order.
+
+*** The Debian installer
+Select the =install= option (not the =Graphical install=) in the GRUB bootloader.
+
+To navigate the menus, use arrow keys and TAB, to toggle check boxes use spacebar and to press button use the enter key.
+
+Simple guide:
+1. Select region
+2. Select localization (US)
+3. Select keyboard layout (most likely US/ISO)
+4. Select connected if you have Ethernet connection or wireless if you
+   want to connect to wifi.
+5. Choose hostname.
+6. Skip domain name.
+7. Skip proxy.
+8. Select mirror in your region.
+9. Set root password.
+10. Set user's full name, username and password.
+11. Deselect all software packages except base.
+12. To dual boot with Windows select guided partitioning (free space).
+13. Select =/home= folder on a separate partition.
+14. Start the installation.
+15. Reboot and check that you can boot everything.
+
+* Setting up GNU/Linux
+** User setup
+1. Login as root
+1. Edit =/etc/apt/sources= and add =non-free contrib testing unstable=
+2. ~apt udpate~
+3. ~apt upgrade~
+4. ~apt install sudo~
+5. ~visudo~ (%wheel ALL=(ALL) NOPASSWD: ALL)
+6. ~groupadd wheel~
+7. ~usermod -aG wheel YOUR_USERNAME~
+8. ~exit~
+
+** Environment setup
+*** Folder setup
+#+begin_src sh
+cd
+rmdir Downloads Desktop ...
+mkdir downloads documents multimedia
+cd multimedia
+mkdir screenshots
+mkdir screencasts
+#+end_src
+
+*** Emacs setup
+~sudo apt install emacs git vterm-module libtd~
