+# export-files.sh
+
+This script can be used to download all files from docspell that have
+been uploaded before.
+
+# Requirements
+
+It is a bash script that additionally needs
+[curl](https://curl.haxx.se/) and
+[jq](https://stedolan.github.io/jq/).
+
+# Usage
+
+```
+./export-files.sh <docspell-base-url> <target-directory>
+```
+
+For example, if docspell is at `http://localhost:7880`:
+
+```
+./export-files.sh http://localhost:7880 /tmp/ds-downloads
+```
+
+The script asks for your account name and password. It then logs in
+and goes through all items downloading the metadata as json and the
+attachments. It will fetch the original files (not the converted
+ones).
