+## My list
+
+- `aminda-desktop.conf` protects packages I consider essential for my desktop
+  experience, mainly `sway` and `waybar`, the latter which once got removed
+  due to dependency issue with Fedora 40 during its rawhide days and that was
+  a bit painful.
+- `aminda-essentials.conf` protects essential packages that are CLI, mainly
+  `tmux`, `git` and `zsh` at this time.
+- `README.md` explains what these files are about and is the file you are
+  currently reading, isn't it?
+- `{sdubby,systemd-boot-unsigned}.conf` are required and recommended to be
+  protected for `systemd-bootd` when not using `grub`.
+- `systemd-{networkd,resolved}.conf` protect the two which I use for
+  `resolv.conf` and network management and I will be unhappy if they vanish
+  mysteriously (Debian testing once stripped systemd-resolved from core
+  systemd and broke my DNS, so just in case...)
+- `unbound.conf` is what I use in addition to `systemd-resolved` recommended
+  or not, so I have at least one working DNS resolver on my system.
