+### Permalinks
+
+Permalinks are currently rather basic and requires JavaScript to be enabled on the local computer.
+In order to identify documents between file changes, a unique identifier is used to identify a file.
+
+This unique identifier can be generated using the `uuidgen` command in the `uuid-runtime` package or
+`str(uuid.uuid())` in the `uuid` python package.
+
+The included `n2w_add_uuid.py` will add a UUID to a markdown file which does not have a UUID in it
+already.
+Combine it with `find` to UUIDify all your markdown files (but make a backup first).
