+virtual-site
+####
+
+Example application showcasing OCS API interactions needed to fulfill
+observation requests at a telescope site.
+
+You might find this helpful if you're looking to integrate your telescope's
+control system with the Observatory Control System. Also, see
+https://observatorycontrolsystem.github.io/integration/tcs/.
+
+Usage
+----
+
+You can spin up the client straight from docker::
+
+  $ docker run ghcr.io/observatorycontrolsystem/virtual-site --help
+  $ docker run ghcr.io/observatorycontrolsystem/virtual-site \
+      --name ogg \
+      --api-url http://localhost:8000/api/ \
+      --api-token 'sutoken1234abcd'
+
+Development
+----
+
+Install dependencies::
+
+  $ poetry install
+
+Run::
+
+  $ poetry run virtual-site --name ogg --api-url http://localhost:8000/api/ --api-token 'sutoken1234abcd'
