+********************************************************************************
+
+Welcome to the Sourcegraph 1-Click App Droplet.
+
+For help and more information, visit https://docs.sourcegraph.com/
+
+## Accessing Sourcegraph
+
+Sourcegraph is running as the sourcegraph/server Docker container with two different access points:
+ - Sourcegraph web app: https://${IP_ADDRESS}
+ - Sourcegraph management console: https://${IP_ADDRESS}:2633
+
+## Controlling Sourcegraph
+
+There are four scripts in the /root directory for controlling Sourcegraph:
+ - sourcegraph-start
+ - sourcegraph-stop
+ - sourcegraph-restart
+ - sourcegraph-upgrade
+
+## Server resources
+
+ - Sourcegraph configuration files are in /etc/sourcegraph
+ - Sourcegraph data files are in /var/opt/sourcegraph
+
+## PostgreSQL access
+
+Access the PostgreSQL db inside the Docker container by running: docker container exec -it sourcegraph psql -U postgres sourcegraph
+
+## Security
+
+To keep this Droplet secure, UFW is blocking all in-bound ports except 20, 80, 443, and 2633 (Critical config management console).
+
+To delete this message of the day: rm -rf $(readlink -f ${0})
