 # My NixOS Flake Config
-My attempt to have one repo and set of config files for both of my NixOS machines.
+My NixOS repo with that has the configs for 2 of my NixOS machines.
 
-My thoughts before is started this are [here](https://blog.arkadi.one/p/nixos-multiple-machine-flake/).
+**Note to self:**
+I have no files in /etc/nixos now. I wonder if I should `ln` them there. Hmm.
 
+## Notes for newbies on how to use this
+1. Change hostnames in the flake
+2. Update things back up to github with:
+```
+git add . #add all files
+git commit -m "Update NixOS config." #commit message
+git push origin main #put updated files in git repo
+```
+3. In the ./nixos-config, deploy this with the command `sudo nixos-rebuild switch --flake .#HOSTNAME`
+
+# Structure of NixOS Config
