+# Helper script to run the integration tests on a fresh Nextcloud server through
+# Docker.
+#
+# The integration tests are run in its own Docker container; the grandparent
+# directory of the integration tests directory (that is, the root directory of
+# the Nextcloud server) is copied to the container and the integration tests are
+# run inside it; in the container the configuration/data from the original
+# Nextcloud server is ignored, and a new server installation is performed inside
+# the container instead. Once the tests end the container is stopped.
+#
+# To perform its job, the script requires the "docker" command to be available.
+#
+# The Docker Command Line Interface (the "docker" command) requires special
+# permissions to talk to the Docker daemon, and those permissions are typically
+# available only to the root user. Please see the Docker documentation to find
+# out how to give access to a regular user to the Docker daemon:
+# https://docs.docker.com/engine/installation/linux/linux-postinstall/
+#
+# Note, however, that being able to communicate with the Docker daemon is the
+# same as being able to get root privileges for the system. Therefore, you must
+# give access to the Docker daemon (and thus run this script as) ONLY to trusted
+# and secure users:
+# https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
+#
+# Finally, take into account that this script will automatically remove the
+# Docker containers named "database-nextcloud-local-test-integration" and
+# "nextcloud-local-test-integration", even if the script did not create them
+# (probably you will not have containers nor images with that name, but just in
+# case).
