 OpenSSH dropbox, with credentials from CentralEGA and RabbitMQ notifications for file system events
+
+
+To build the docker image, use:
+
+	# Create the "lega" group
+	getent group lega || groupadd -g 1001 lega # adjust the number if needed
+
+	# Build the image (using the above group, for access permissions)
+	make latest
+
+You can run a test instance (not connected to a local broker) with:
+
+	docker-compose up -d
+
+However, you first need to get credentials from Central EGA, and add them to the compose file.
