## Set up configuration.nix
First thing you'll need to do is to make your useer account own the
`/etc/nixos` directory. You'll want to do this to allow you to easily manage
your config with git (which is a requirement when using flakes). You can use
system wide git, however it is much more convenient to just leave it to the
user, as you'll have your git configuration there.
```sh
cd /etc/nixos
sudo chmod -R itsdrike:users .
```
Out of the box, NixOS only comes with `nano` editor, so we'll have to use that to edit the `configuration.nix` for the first time.
```sh
nano configuration.nix
sudo nano configuration.nix
```
In there, change the `environment.systemPackages = with pkgs; [];` like, and include `git` and `vim`.

## Set up flakes
Now, since a git repository is required for flakes, let's set up git:
An interesting things about nix flakes, is that they need to live in a git
repository, you won't be able to rebuild otherwise, so let's set up some git
settings, so that we can make commits:
```sh
git config --global user.email "itsdrike@protonmail.com"
git config --global user.name "ItsDrike"
```
We could create and manage this repository directly in `/etc/nixos`, however
that's not practical, since we probably want to use our git config and
generally just work in a non-root environment when editing the flake. I like
using the `~/dots` directory.
```sh
cp -r /etc/nixos ~/dots
cd ~/dots
```
Now we have 2 options, the first one I'll show will set up my configuration
from this repository. Once done, you will have your system set up in the same
way that I do. In the second option, I will go over a basic setup to create

You can notice that this also created a `flake.lock` file, containing the exact
versions of all of the packages you're using. Let's add this file to git too:
