+* System installation
+** Preparation
+In my cases the provided ISO doesn't work because of Libre kernel.
+
+Fortunately, David Wilson has made [[https://github.com/SystemCrafters/guix-installer][a repository]] with a toolchain to make an ISO with the full kernel. In case it won't be an option, the [[https://gitlab.com/nonguix/nonguix][nonguix repo]] also has instructions on how to do that.
+
+When an ISO is there, we have to write it on a USB stick. Run =sudo fdisk -l= to get a list of disks.
+
+The approach in the official instruction is to create a bootable USB with =dd=:
+#+begin_example
+sudo dd of=/dev/sdxX if=<path-to-iso> status=progress && sync
+#+end_example
+
+However, I couldn't make it work for some strange reason. Fortunately, =gnome-disk-utility= was able to produce a bootable USB.
+** Installation
+Going further, the official instructions for installation & SystemCrafters wiki entry are pretty good, so it's not necessary to repeat them here.
+** After installation
+After the installation, the strategy is as follows.
+
+Set a password for the main user (pavel). Login with openbox to get a tolerable interface, because i3 default config is horrible.
+
+[[https://guix.gnu.org/en/manual/en/html_node/Keyboard-Layout-and-Networking-and-Partitioning.html#Keyboard-Layout-and-Networking-and-Partitioning][Connect to the internet]].
+
+Clone the dotfiles repo:
+#+begin_example
+mkdir Code
+cd Code
+git clone https://github.com/SqrtMinusOne/dotfiles.git
+#+end_example
+
+Copy the channels file and run guix pull:
+#+begin_example
+cp ~/Code/dotfiles/.config/guix/channels.scm ~/.config/guix
+guix pull
+#+end_example
+
+The first pull usually takes a while. After that install yadm and pull dotfiles:
+#+begin_example
+guix install yadm
+guix clone https://github.com/SqrtMinusOne/dotfiles.git
+#+end_example
+
+And activate the required profiles. Again, downloading & building Emacs, Starship and stuff will take a while.
+
+Don't forget to install =JetBrainsMono Nerd Font=.
