+== Scope
+
+Describe how snapshot.r-b.o has been set up on a dedicated machine
+hosted at OSUOSL.org
+
+=== initial setup
+
+I follewed https://github.com/fepitre/debian-snapshot#installation and
+added the needed packages to update_jdn.sh in this git repo.
+
+https://github.com/fepitre/debian-snapshot was cloned into ~jenkins/debian-snapshot/
+
+sudo cp ~jenkins/debian-snapshot/api/snapshot-api.service /usr/lib/systemd/system
+and adopted two lines:
+	User=jenkins
+	WorkingDirectory=/var/lib/jenkins/debian-snapshot/api
+
+sudo systemctl daemon-reload
+sudo mkdir -p /snapshot /var/run/snapshot /var/log/snapshot
+sudo chown jenkins:www-data /var/run/snapshot
+sudo chown postgres:postgres /var/lib/postgresql
+sudo chown jenkins:jenkins /var/log/snapshot
+
+nginx.conf from ~jenkins/debian-snapshot/api/nginx.conf has been copied into this
+git repo so we can maintain our copy here.
