### Channels
For `nix` to be able to install packages it is necessary to add a few channels:
```
$ nix-channel --add https://nixos.org/channels/nixos-23.11 nixos
$ nix-channel --add https://nixos.org/channels/nixpkgs-unstable nixpkgs
$ nix-channel --update
```
## Usage
Nix can be used to manage your `$HOME` with `home-manager` and `flakes`. ([Here a link explaining it all](https://juliu.is/tidying-your-home-with-nix/))
Now that Nix is up and running utilize the `flake` that comes with the [config files](https://docs.bijl.us/alpine-desktop-setup/post-install/config-files/) to set up our home for us. But before initialising `nix` make sure that you set the correct `<username>` in both `flake.nix` and `home.nix` which are located in `~/.config/home-manager`. Then after changing those simply run this command from that same directory:
Nix can be used to manage your `$HOME` with `home-manager`. First install `home-manager` through:
```
$ nix run . switch
$ nix-env -iA nixos.home-manager
```
This should have installed `nixpkgs-unstable` and `home-manager`. Verify this with:

You can also test a package before installing it with `nix-shell -p <program>`

### Nix-Bubblewrap
### NixGL
`nixGL` will be necessary to be able to run graphical programs which are installed through `nix`. Add it's channel and install it with:
```
$ nix-channel --add https://github.com/nix-community/nixGL/archive/main.tar.gz nixgl && nix-channel --update
$ nix-env -iA nixgl.auto.nixGLDefault nixgl.VulkanIntel
