+# Configuration for the library laptops
+
+To apply this configuration, run:
+
+``` shell
+sudo nixos-rebuild switch --flake git+https://codeberg.org/foss-for-normies/library-laptops-configuration
+```
+
+
+## Changing the configuration
+
+Clone this repository on one of the laptops. Change whatever you need. Switch to a new configuration:
+ 
+``` shell
+sudo nixos-rebuild switch --flake .
+```
+
+Reboot and make sure everything works as expected. Then push to the upstream repository for the new configuration to be applied.
+
+
+## Updating the OS
+
+Similar to changing the configuration:
+
+``` shell
+nix flake update
+sudo nixos-rebuild switch --flake .
+```
+
+Then reboot and check if everything still works. If so, push:
+
+``` shell
+git add flake.lock
+git commit --message "Update NixOS"
+git push

Dump some tasks to TODO.md

Probably we want them in an issue tracker, so we can have discussion and outside input, but as a quick solution I just wrote them in a file.
