 ## Adding Files
 
-**Edit the script** — add paths to the `DOTFILES` array in `dot-backup.sh`.
-
-**Or use the external list** — add paths to `~/.config/dot-backup/files.list`, one per line:
+**External list (recommended)** — create `~/.config/dot-backup/files.list` with one path per line. When this file exists and is non-empty it replaces the built-in list entirely:
 
 ```
-# extra dotfiles
-.config/myapp
-.config/otherapp.conf
+# shell
+.bashrc
+.bash_aliases
+
+# system files
 /etc/hosts
+/etc/fstab
 ```
 
+**Built-in fallback** — if `files.list` is missing or empty, the script uses the `DOTFILES` array hardcoded in `dot-backup.sh`.
+
 Relative paths are treated as `$HOME`-relative. Absolute paths (starting with `/`) are treated as system files.
