NixOS profiles to optimize settings for different hardware.

## Setup

### Using channels

Add and update `nixos-hardware` channel:

```
$ sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
$ sudo nix-channel --update
```

Then import an appropriate profile path from the table below. For example, to
enable ThinkPad X220 profile, your `imports` in `/etc/nixos/configuration.nix`
should look like:

```
imports = [
  <nixos-hardware/lenovo/thinkpad/x220>
  ./hardware-configuration.nix
];
```

New updates to the expressions here will be fetched when you update the channel.

## Using nix flakes support

There is also experimental flake support. In your `/etc/nixos/flake.nix` add the following:

```nix
{
  description = "NixOS configuration with flakes";
  inputs.nixos-hardware.url = github:NixOS/nixos-hardware/master;

  outputs = { self, nixpkgs, nixos-hardware }: {
    # replace <your-hostname> with your actual hostname
    nixosConfigurations.<your-hostname> = nixpkgs.lib.nixosSystem {
      # ...
      modules = [
        # ...
        # add your model from this list: https://github.com/NixOS/nixos-hardware/blob/flakes/flake.nix
        nixos-hardware.nixosModules.dell-xps-13-9380
      ];
    };
  };
}
```


### Using fetchGit

You can fetch the git repository directly:

```nix
imports = [ 
  "${builtins.fetchGit { url = "https://github.com/NixOS/nixos-hardware.git"; }}/lenovo/thinkpad/x220"
];
```

Unlike the channel, this will update the git repository on a rebuild. However, 
you can easily pin to a particular revision if you desire more stability.

## How to contribute a new device profile

1. Add your device profile expression in the appropriate directory
2. Link it in the table in README.md and in flake.nix
3. Run ./tests/run.py to test it. The test script script will parse all the profiles from the README.md
