 These are my configurations for nixos. You are free to use it, however it may be best for you to fork and make your own.
 
 ## Installing
-In my experience, you need a larger disk size for the nix store on the installer than is created. As such, I use a NFS mount with a swap file. If you are installing using an USB stick, you can probably place a swap file there.
+In my experience, you need a larger disk size for the nix store on the installer than is created. As such, I use a swap file/drive, recommended separate drive from the one being installed to.
+
+### Swap example.
 
 ```bash
-nix-shell -p git nfs-utils
-mkdir /mnt/merged
-mount.nfs 10.0.0.5:/mnt/merged /mnt/merged
-mkdir /mnt/merged/nixos-tmp
-fallocate -l 30G /mnt/merged/nixos-tmp/swap
-chmod 600 /mnt/merged/nixos-tmp/swap
-mkswap /mnt/merged/nixos-tmp/swap
-swapon /mnt/merged/nixos-tmp/swap
+mkdir /mnt/usb
+mount /dev/sdb1 /mnt/usb
+fallocate -l 30G /mnt/usb/swap
+chmod 600 /mnt/usb/swap
+mkswap /mnt/usb/swap
+swapon /mnt/usn/swap
 mount -o remount,size=20G,noatime /nix/.rw-store
-git clone --recursive https://github.com/GRMrGecko/nixos.git
+```
+
+### The install process.
+
+After setting up the extra swap space, clone and enter the nixos repo.
+```bash
+nix-shell -p git
+git clone --recursive https://github.com/GRMrGecko/nixos.git
+cd nixos/
+```
+
+After you get into the repo, configure the machine to your liking.
+```bash
+./configure.sh
+```
+
+After configuring, install. You can define a tmpdir as the USB drive with `TMPDIR=/mnt/usb` if you want to reduce load on RAM.
+```bash
+./install.sh --disk main /dev/sda
+```
+
+After install is complete, you can then rsync the nixos dir to the user account on the install:
+```bash
+nix-shell -p rsync
+mount -o compress=zstd /dev/mapper/crypted /mnt/hdd
+rsync -av /root/nixos/ /mnt/hdd/home/grmrgecko/nixos/
 ```
