+# Docker Compose file for running paperless from the docker container registry.
+# This file contains everything paperless needs to run.
+# Paperless supports amd64, arm and arm64 hardware.
+#
+# All compose files of paperless configure paperless in the following way:
+#
+# - Paperless is (re)started on system boot, if it was running before shutdown.
+# - Docker volumes for storing data are managed by Docker.
+# - Folders for importing and exporting files are created in the same directory
+#   as this file and mounted to the correct folders inside the container.
+# - Paperless listens on port 8000.
+#
+# In addition to that, this Docker Compose file adds the following optional
+# configurations:
+#
+# - Instead of SQLite (default), PostgreSQL is used as the database server.
+# - Apache Tika and Gotenberg servers are started with paperless and paperless
+#   is configured to use these services. These provide support for consuming
+#   Office documents (Word, Excel, Power Point and their LibreOffice counter-
+#   parts.
+#
+# To install and update paperless with this file, do the following:
+#
+# - Copy this file as 'docker-compose.yml' and the files 'docker-compose.env'
+#   and '.env' into a folder.
+# - Run 'docker compose pull'.
+# - Run 'docker compose run --rm webserver createsuperuser' to create a user.
+# - Run 'docker compose up -d'.
+#
+# For more extensive installation and update instructions, refer to the
+# documentation.
