# Bootstrapping a New Device
This guide assumes you have a somewhat sane sops setup.
1. First, boot the NixOS live environment (minimal ISO is recommended).
2. Then, get the harddrive ID using `lsblk` or `fdisk -l`:
```bash
sudo fdisk -l
ls -lah /dev/disk/by-id | grep -i <drive disk ID ie. sda>
```
Example output:
```bash
[nix-shell:~]$ sudo fdisk -l
Disk /dev/loop0: 1.14 GiB, 1221455872 bytes, 2385656 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk /dev/sda: 256 GiB, 274877906944 bytes, 536870912 sectors
Disk model: QEMU HARDDISK
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
[nix-shell:~]$ ls -lah /dev/disk/by-id | grep -i sda
lrwxrwxrwx 1 root root 9 May 5 13:20 scsi-0QEMU_QEMU_HARDDISK_drive-scsi0 -> ../../sda
[nix-shell:~]$ # disk path: /dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi0
```
3. Manually create a host configuration by modifying/duplicating `hosts/<target_host_to_base_off_of>` to `hosts/<new_host_name>`. Be sure to modify the hostname in `hosts/<new_host_name>/configuration.nix`.
4. Add the host to `flake.nix`.
5. Modify the disko configuration for our host to use the correct disk ID that we found earlier.
6. Make any other additional modifications if needed.
