+been uploaded before and the item metadata.
+
+It downloads the original files, those that have been uploaded and not
+the converted pdf files.
+
+The item's metadata are stored next to the files to provide more
+information about the item: corresponent, tags, dates, custom fields
+etc. This contains most of your user supplied data.
+
+This script is intended for having your data outside and independent
+of docspell. Another good idea for a backup strategy is to take
+database dumps *and* storing the releases of docspell next to this
+dump.
+
+Files are stored into the following folder structure (below the given
+target directory):
+
+```
+- yyyy-mm (item date)
+  - A3…XY (item id)
+    - somefile.pdf (attachments with name)
+    - metadata.json (json file with items metadata)
+```
+
+By default, files are not overwritten, it stops if existing files are
+encountered. This and some other things can be changed using
+environment variables:
+
+- `DS_USER` the account name for login, it is asked if not available
+- `DS_PASS` the password for login, it is asked if not available
+- `OVERWRITE_FILE=` if `y` then overwriting existing files is ok.
+  Default is `n`.
+- `SKIP_FILE=` if `y` then existing files are skipped (supersedes
+  `OVERWRITE_FILE`). Default is `n`.
+- `DROP_ITEM=` if `y` the item folder is removed before attempting to
+  download it. If this is set to `y` then the above options don't make
+  sense, since they operate on the files inside the item folder.
+  Default is `n`.
+
+Docspell sends the sha256 hash with each file via the ETag header.
+This is used to do a integrity check after downloading.
