 Don't bother installing krita/cuda, the process is too in depth and time
 consuming, if you really need krita/obs-studio, just use flatpak. If you really
 need Cuda, consider using Vulkan instead (for llama.cpp).
+
+## After Installation
+
+There's a lot to do after installation, but one of the first things you should
+do is:
+
+**Create a New SuperUser**
+
+```sh
+adduser $USER &&
+useradd -aG wheel $USER
+```
+
+In package.use add:
+
+```sh
+app-admin/doas persist
+```
+
+Then install `doas`:
+
+```sh
+emerge -av app-admin/doas
+```
+
+Edit `/etc/doas.conf`:
+
+```sh
+permit persist :wheel
+```
+
+Test it:
+
+```sh
+su $USER
+doas emerge -av <some-package>
+```
+
+## Install openrc-init as PID 1
+
+By default, while Gentoo does use openrc as the service manager, it does not use
+it as init, rather wrapping SysVInit instead. OpenRC does have an init package
+however that can be used as init, it just has some caveats.
+
+[See The Gentoo Wiki For Full Details](https://wiki.gentoo.org/wiki/OpenRC/openrc-init)
+
+Make sure your system is running fine under sysvinit before proceeding.
+
+Openrc-init is installed by default, no need to emerge.
+
+You just need to change this line in your `/etc/default/grub`:
+
+```
+#GRUB_CMDLINE_LINUX_DEFAULT=""
+GRUB_CMDLINE_LINUX_DEFAULT="init=/sbin/openrc-init"
+```
+
+And, of course, regenerate:
+
+```sh
+grub-mkconfig -o /boot/grub/grub.cfg
+```
+
+You'll need to reinstantiate the tty's though:
+
+```sh
+cd /etc/init.d
+for n in $(seq 1 6); do ln -s agetty agetty.tty$n; rc-update add agetty.tty$n default; done
+```
+
+Then reboot to have it take effect.
+
+```sh
+reboot
+```
+
+Note that some aliases for shutting down and rebooting in your `.aliases` file
+are helpful here:
+
+```sh
+alias shutdown="doas openrc-shutdown -p 0"
+alias reboot="doas openrc-shutdown -r 0"
+```
+
+## Common packages
+
+There are tons of packages I like, but a few that will be necessary once X11 is
+installed are:
+
+[Matcha Themes](https://github.com/vinceliuice/Matcha-gtk-theme)
+[Papirus Icon Theme](https://packages.gentoo.org/packages/x11-themes/papirus-icon-theme)
+[Gobble Window Swallower](https://github.com/EmperorPenguin18/gobble/)
