+# Introduction
+
+Coming from
+[paperless](https://github.com/the-paperless-project/paperless/), the
+script in `tools/import-paperless` can be used to get started by
+importing your data from paperless into docspell.
+
+<https://github.com/eikek/docspell/tree/master/tools/import-paperless>
+
+The script imports the files and also tags and correspondents.
+
+# Usage
+
+Copy the script to the machine where paperless is running. Run it with
+the following arguments:
+
+1. URL of Docspell, including http(s)
+2. Username for Docspell, possibly including Collective (if other name as user)
+3. Password for Docspell
+4. Path to Paperless' database file (`db.sqlite3`). When using Paperless with docker, it is in the mapped directory `/usr/src/paperless/data`
+5. Path to Paperless' document base directory. When using Paperless with docker, it is the mapped directory `/usr/src/paperless/media/documents/origin/`
+
+Some settings can be changed inside the script, right at the top:
+
+* `LIMIT="LIMIT 0"` (default: inactive): For testing purposes, limits
+  the number of tags and correspondents read from Paperless (this will
+  most likely lead to warnings when processing the documents)
+* `LIMIT_DOC="LIMIT 5"` (default: inactive): For testing purposes,
+  limits the number of documents and document-to-tag relations read
+  from Paperless
+* `SKIP_EXISTING_DOCS=true` (default: true): Won't touch already
+  existing documents. If set to `false` documents, which exist
+  already, won't be uploaded again, but the tags, correspondent, date
+  and title from Paperless will be applied.
+
+  **Warning** In case you already had set these information in Docspell,
+  they will be overwritten!
