+# 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.
