+Now you can reboot and progress to the post install.

 # Post install
 
-TODO: adding a user and git.
+Now, you can log into the root user.
+
+First of, time to add a user.
+This can be done in `/etc/nixos/configuration.nix` by adding the following (The editor **nano** is installed by default):
+```nix
+users.users.<name> = {
+  isNormalUser = true;
+  extraGroups = [ "wheel" ]; #Enables sudo for the user;
+  packages = with pkgs; [
+  ];
+}
+```
+Please change `<name>` to the username you want, and then run `nixos-rebuild switch --flake .#nixos -L` to rebuild the system with the user added.
+Then run `passwd <name>` to change their password.
+
+Logout and login to your new user.
+
+It is now time to make this version controlled.
+Run `cp -r /etc/nixos dots` to copy the configuration to the local folder dots.
+Then run `cd dots` and edit `configuration.nix` by adding:
+```nix
+environment.systemPackages = with pkgs; [
+  git
+  neovim # or another editor if you want
+];
+```
+Then run `nixos-rebuild switch --flake .#nixos -L`.
+Now you have git and another editor installed globally.
+Time to run `git init && git add .` to save your current config.
+Now, if you add files that are used by your configuration but not added to git, the rebuild will fail.
+This is done to ensure a rebuildable system.
+But remember, do not include secrets within your configuration, unless you have a good system.
+
+After fixing a good setup, please setup a remote for git, so that you are able to rebuild when needed, or just share your magnificent setup.

 With this you have an installed system, with a user, but not much more.
