12 The arvados-ws server provides event notifications to websocket clients. It can be installed anywhere with access to Postgres database and the Arvados API server, typically behind a web proxy that provides SSL support. See the "godoc page":http://godoc.org/github.com/arvados/arvados/services/ws for additional information.

36 The arvados-ws service will be accessible from anywhere on the internet, so we recommend using SSL for transport encryption.
37
38 Use a text editor to create a new file @/etc/nginx/conf.d/arvados-ws.conf@ with the following configuration.  Options that need attention are marked in <span class="userinput">red</span>.
