 - `sigil add <path>` — add a file/dir to the repo and symlink it

 ## Notes
+
 - If a repo file is missing, stale links should be pruned.
 - Prefer `sigil add` over manual moves into `files/`.
+
+# Editing dotfiles
+
+When editing dotfiles, it is preferred to add/edit the files in this project directly, instead of going to the source. this way we can then use sigil apply --prune, and everything will be synced, even when there are new files.
