-### StrongOps support
-If you would like to monitor your application there is a default support for [StrongOps](http://strongloop.com/node-js-performance/strongops/) monitoring.

-You can enable profiling by either:
-- use a `strongloop.json` configuration file
-- set `ENV` variables before running the app
-
-```bash
-SL_KEY=<API_KEY> SL_APP_NAME=sphere-express-pdf slc run |bunyan -o short
