# Prerequisites

## Required Tools

Ensure you have the following tools installed on your local machine:

| Tool | Purpose |
|------|---------|
| `nix` | Package manager with flakes enabled |
| `sops` | Secret encryption/decryption |
| `age` | Encryption backend for sops |
| `ssh` | Remote access |

### Installing Nix

Follow the [official Nix installation guide](https://nixos.org/download/).

Enable flakes by adding to `~/.config/nix/nix.conf`:

```
experimental-features = nix-command flakes
```

### Installing Other Tools

With Nix:

```bash
nix-shell -p sops age
```

Or install globally via home-manager or system configuration.

## Repository Access

Clone the repository:

```bash
git clone https://git.cryodev.xyz/steffen/cryodev-server.git
cd cryodev-server
```

## Development Shell

Enter the development shell with all required tools:

```bash
nix develop
```

## Verifying Setup

Check that the flake is valid:

```bash
nix flake check
```

Build a host configuration (dry run):

```bash
nix build .#nixosConfigurations.cryodev-main.config.system.build.toplevel --dry-run
```
